Background technology
The fibre-composite component that long fibre strengthens is an important use field of technical fabrics.The structure of enhancing fabric and tissue match with the host material of manufacturing process and application and determine the characteristic of later composite component fatefully.Above-mentioned multi-axial fabric, same MD or multidirectional fabric play an effect especially at this, allow planar structure because compare it with other fabric, it provides the higher utilization of the distinctive characteristic of applied fiber, thereby reduces manufacturing cost simultaneously and reduce the member cost.
Use different technology in order to make multi-axial fabric.One approaching technology is to adopt one to be similar to woven method, and wherein the bearing of trend with a weft yarn and webs lays at angle.But this method is slowly and allows little manufacturing speed when fine fibre.Below a kind of method proved and can make significantly quickly, in the method above-mentioned single shaft is become a multi-axial fabric to fabric, same UD or unidirectional fabric by the winding shaping around a plane.
A kind of method that is used to make a multidirectional webs is disclosed in open text DE 10 2,005 000 115A1, wherein in the method around a fiber along the fabric of the bearing of trend orientation of webs with two other the webs of reeling at angle with respect to bearing of trend, form a multi-axial fabric simultaneously.Therefore this multi-axial fabric has at least three layers.They are two opposed layer and so-called zero degree webs of the fabric of reeling at angle, and the latter has along the fiber of the bearing of trend of webs.One such fabric has the favourable characteristic about tensile strength.
Japanese patent application JP2003221771A is open about a kind of method that is used to make a multiaxial contexture web, wherein has only around the two wide silk ribbon of hand a plurality of webs of reeling at angle of reeling roughly, and they remain in the fabric.Form a multi-axial fabric by this method, it has each edge that strengthens.Each edge that strengthens has following advantage on the one hand: fabric has a high toughness or a high stability especially on each edge whereby, this fabric has following shortcoming on the other hand: because the material thickness that increases on each edge, material can not stably be wound up on the roller and therefore can not constitute the uniform layer thickness of fibre-reinforced plastics on the other hand, because the band of each side has unnecessarily increased the thickness of fabric.
Summary of the invention
Therefore the objective of the invention is, a kind of method that is used to make multi-axial fabric is provided, it overcomes shortcoming of the prior art.
By adopting many each tension elements to reach purpose of the present invention as the boundary on plane, unidirectional fabric is reeled around this plane, and is wherein removable or separate each tension element after the coiling of the webs of making like this.Draw other favourable form of implementation of the present invention by all dependent claims.
Compare with disclosed method among JP 2003 221771A, adopt the tension element of a pair of tension, the coiling plane of each webs that they are provided with as the bearing of trend that favours fabric according to the present invention.Form a multiaxial contexture web whereby, they at first only loosely adhere to mutually, and are extended later at the coiling by two calendering rollers.Make a plurality of corresponding grooves in each calendering roller, each tension element moves therein, thereby can be independent of the spacing of each calendering roller of size Selection of each tension element.The calendering roller engages each webs securely, makes it constitute a firm multi-axial fabric by the application of adhesive or adhesive where necessary.Might make fabric with tension element or do not have tension element and stand a dip bonding method or a method for shaping in addition, whereby in order to continue to process the fabric and be easy to operate of to reel.After calendering or dipping, can multiaxial contexture web be separated with each tension element by the cutting at an edge immediately.At each tension element that this cutting step will remove or be wound on another cylinder, this moment, each tension element selectively can also be broken away from the fiber that adheres on each tension element before reeling.But possible equally, each tension element replaces reeling again in the return course, thereby each tension element guides in a continuous loop wire.Possible in addition, each tension element and after each webs unwinding of making by multi-axial fabric of reeling can be with each tension element of reeling return course again, by on a unwinding roller it being supplied with production process again.Possible in addition, replace being separated in and continue to add man-hour and from fabric, pull out each tension element, as long as guarantee not take place the adhesion of fabric on each tension element.
Unidirectional fabric is supplied with the coiling plane transverse to bearing of trend, wherein for example between the bearing of trend and the direction of the supply, can press from both sides angle at 45.But also can press from both sides into other the angle between 0 ° and 90 ° as requested.What can also meet purpose is, supplies with three web of a single shaft to fabric, and it for example is positioned at each single shaft of laterally supplying with between fabric.Therefore three layers the multi-axial fabric that produces is specially adapted to bear the tension along the longitudinal extension of multi-axial fabric, and it is for example because multi-axial fabric pulling out and may produce from the coiling plane.Should be additional the 3rd layer can be by constituting to the fabric identical materials or by another material that is fit to the single shaft that tilts to supply with.Therefore can for example supply with a gluing graticule mesh or adhere to graticule mesh, borrow its single shaft can glue together mutually to each layer that is adjacent to mutually of fabric as the 3rd layer.
In addition advantageously, each groove in the outer surface of calendering roller is constituted in this wise, the pulling force that produces in multi-axial fabric is along the longitudinal direction only occurred in the zone of each groove, that is occur in the zone of each tension element that is arranged in the multi-axial fabric, and the part of remaining multi-axial fabric that is provided with between each tension element in the centre keeps stressless basically.This form of implementation can be made a high-quality multi-axial fabric with method in a simple manner.
Suggestion in addition, multi-axial fabric is handled by means of a porcupine roller or a shank after calendering, that is be provided with a plurality of meshes, it is provided for can entering well in the multi-axial fabric at the resin that this adopted when the later resinification that multi-axial fabric may occur, so that the material of the high-quality as far as possible of even quality is provided.Can go in the multi-axial fabric by extremely different style systems as requested at this mesh of in multi-axial fabric, making.
In order to implement to have two different possibilities on this methodological principle.In one first possibility, in method, adopt two rollers, preset the unidirectional fabric of fibrous material thereon.This two roller is on the axle of a rigidity.Be oppositely arranged each roller at this, extract unidirectional fabric and between each roller, constitute a device by it, two tension elements of unwinding therein, described tension element as one be used for unidirectional fabric the coiling plane boundary and by the guiding of two calendering rollers.Can remove each tension element at this before calendering, wherein each calendering roller gives the mechanical tension of fabric necessity.Perhaps can remove each tension element later in calendering.Then make two tension elements around one at the center and be parallel to the axle rotation of two tension elements and like this by each roller unwinding single shaft to fabric, each roller provides single shaft to fabric, and winds the plane that is made of two tension elements and reel.Along with the plane that rotates with two tension elements, a pair of calendering roller and be near the also also rotation of each device of rotation together each calendering roller, each device before calendering or later on for example remove each tension element by cutting from the edge of multi-axial fabric.Be parallel to that multi-axial fabric is reeled or return course again at this each tension element.One optional step is to remove fiber and the adhesive residue that stays on the tension element that downcuts.Owing in multi-axial fabric, be formed on the open fiber in side by cutting, proved advantageously, by each lateral edges of a corresponding device thereof seam multi-axial fabric, thereby fabric may be not easy to be unfavorable for processing multi-axial fabric thus on the diffusing limit of each side.
Also possible in second form of implementation of method of the present invention, keep unwinding regularly and the whole device of each tension element of reeling again, calendering roller to cutting and stitching devices, and two rollers that have unidirectional fabric are reeled around the plane of each tension element.
Exist the plane that is made of each tension element to have the relative motion of single shaft to the material of fabric relatively in two embodiments, this material is preset on each roller and is wound up on the plane.
In order to stablize winding process, in a preferred form of implementation of method of the present invention, set: each tension element plucking or each tension element are provided with an adhesive or adhesive.The result that the plucking of each tension element or the adhesive of each tension element or adhesive coating produce is, each tension element is caught fabric more reliably, make multi-axial fabric by it, the result of this generation is that be shaped the equably fabric of formation like this and the unidirectional fabric of unwinding are not easy to still landing during calendering process and back to back separation process.In this another form of implementation, also can adopt a fabric with adhesive seldom, thereby each staggered single shaft of reeling adheres to and forms a more firm webs mutually to fabric in method of the present invention.Also possible at this, use a so-called prepreg as raw material, wherein each fiber is provided with the adhesive or a unpolymerized adhesive of hardening not yet, and it can choose sclerosis wantonly in an optional later process.Also might adopt an adhering fibre graticule mesh in order to stablizing each webs in addition, with its unwinding or guiding and interconnect each web between each tension element.
One multiaxial contexture web of making like this can be made by different fibrous materials.Might adopt the raw material of bonding fabric, can adopt textile, knitted fabric, but also can adopt ultimate fibre, glass strand, yarn or the fibrage of the unidirectional or multidirectional setting of supatex fabric as multiaxial contexture web.
The material that constitutes fiber can be glass, carbon or aramid fibre, perhaps can adopt natural fiber, as flax, jute or sisal hemp.Also might adopt plastic optical fibre, as polypropylene, PBO, polyester or polyethylene.
Applied tension element can be made of wire or silk ribbon, and it is in case of necessity by the metal manufacturing.Perhaps might adopt plastics, preferably also be used for textile material this moment, thereby also the fabric finished might be supplied with the production process of continuation with each tension element.Certainly do not need in this case each tension element is separated with fabric.
In order to implement this method one device is set, it is provided with at least one take up roll that is used for fibrous material, a calendering device and separator and a plurality of coiling of each tension element and each roller of unwinding of being used in case of necessity, wherein each tension element parallel opening unwinding and therefore remaining in the plane from each roller tightly, they constitute this plane so that around its coiling fabric.Device can be connected with a separator in addition, from just removing each tension element in short-term later at winding process.Perhaps might be by immersion system guiding fabric together with each tension element, thus after finishing sclerosis, make a flexibility but stable fabric itself.Can remove each tension element after the immersion system at the latest or remain in the fabric by the situation that textile material constitutes for itself.
The invention still further relates to a kind of in order to make the method for a multiaxis to the fabric that preferably constitutes by carbon fibre material, wherein the single shaft of at least one storage device is reeled around a coiling plane to fabric, reel this moment plane and described at least one storage device rotates mutually, so that to fabric, and one in order to implement the corresponding device thereof of the inventive method around coiling plane coiling single shaft.
Adopt the fabric of being made by fiber in order to make fibre-reinforced plastics, it uses a plastic encapsulation.Plastics and fiber be compounded in the stability that this gives the high relative tension of fibre-reinforced plastics one, wherein tension stability depends on the orientation of the fiber that exists in fabric.The occasion that fibre-reinforced plastics are used in particular for requiring a high bearing capacity to combine with small weight is for example in aircraft manufacturing or shipbuilding.For be equipped with fibre-reinforced plastics with an as far as possible little weight essential be, the amount of plastic that is coated on the fiber keeps few as much as possible, wherein plastics should surround fiber fully.Compare the thicker fibrage of coating with the diameter of fiber and also have a plastics requirement that improves thus when adopting the fiber of weaving, it causes one to have the fibre-reinforced plastic member of big layer thickness and therefore cause big weight.Therefore people's fabric of turning to employing to be made of fibrous material in practice is provided with each fiber therein equably and does not intersect mutually, thus so that the plastics requirement that keeps the increase of as far as possible little layer thickness whereby and keep the least possible fibrous material.Because known, plastics only have a high tensile strength along machine direction, adopt multi-axial fabric, wherein lay fiber in a plurality of planes, wherein fiber has a preferred orientations and does not intersect mutually by possibility in each plane.The multi-axial fabric that the utmost point is made simply like this is a fabric, lays two webs of a fiber alignment therein juxtaposition.This fabric is so made, therein or the each several part of a webs lays mutually at angle with web respectively, wherein at first the layer below one and then the layer above merge by various piece.At this moment each assembly of being made up of parallelogram is merged the web of growing up.But this method is not suitable for the bigger quantity of manufacturing economically, needs in the manufacture process of industry as it.
Therefore people turn to the yarn volume of pulling out such formation at angle around a coiled sheet in one or two web and slave plate in other method.This process can be implemented continuously, and pull out the yarn volume and and then be compacted into a fabric this moment in the slave plate.One such method has proved in practice and has been difficult to controllablely, and particularly as under the situation of carbon fiber, fiber has a similar performance that flows.This means that each fiber is because its small weight and its small friction from the teeth outwards are superimposed easily and therefore hinder the formation of a webs that evenly is shaped.The flowability of the performance of one fabric is big more, and is difficult more in the manufacturing of this multi-axial fabric that evenly is shaped.What need when winding board is reeled is, is arranged in the nethermost fabric of plate and is not easy to make each fiber slave plate unwinding and therefore has one twistedly when slave plate is pulled out continuously, and it causes each fiber crossing or intersection later on pulling out fabric.Intersect that to make fabric be bad up to being obsolete comparing with an achiasmate multi-axial fabric that evenly is shaped qualitatively.If fabric is stretched in strongly on the coiling plate and reels, the unwinding of fiber then especially appears.If opposite fabric winding board loosely lays, then each fiber might be on slave plate intersects mutually during landing or constitutes loop wire.This also causes in bad or obsolete result qualitatively.
The objective of the invention is, a kind of apparatus and method are provided, is multi-axial fabric with a single shaft to the winding shaping of fabric by winding board wherein, intends avoiding friction by possibility when wherein pulling out the yarn volume on slave plate, so that obtain a multi-axial fabric that evenly is shaped.
Reach purpose of the present invention by at least one band transmission of the application on the opposed side on coiling plane, draw other favourable form of implementation of the present invention by all dependent claims.
Have so big thickness around its single shaft of reeling to the coiling plane of fabric, and make and in the plate that is used as the coiling plane, a belt driver can be set.Though enlarge markedly the thickness on coiling plane thus, thereby yarn twists in and form a cylindraceous fabric when pulling out from the coiling plane, it must be configured as a fabric in another step, but the outside dimension of band transmission on the opposed side on coiling plane can be provided with a machinery, and it allows not have fully frictionally pulls out the yarn volume from the coiling plane.Fiber does not slide and also not unwinding from it on a surface, and the band transmission is fed forward the yarn volume continuously and the end of while on the coiling plane discharges the yarn volume.The form of implementation that is different from the low friction on a coiling plane, for example by utilizing the coating on a surface, it has a small frictional resistance, here sets, and constitutes the coiling plane by preferred at least one belt driver.
In favourable form of implementation of the present invention, set, the intersection guiding of a driving-belt is set in method and in corresponding device thereof for this reason, wherein on the opposed side on coiling plane, freely guide driving-belt.The forward travel that intersection guiding by driving-belt is implemented on the opposed side on coiling plane is fully uniformly.Therefore can economize the sychronisation of abandoning two forward travels, this causes a structure according to the simplification of machinery of the present invention.Owing to it is important that the coiling plane has an identical speed at any time, avoids the twisted of each fiber by being synchronized with the movement of two sides whereby during the forward travel on the opposed side on coiling plane.Intersection guiding by a driving-belt or a wide band reaches, and driving-belt is provided with between two outward flanges or coiling face at the center, is equal length at the stroke on two outward flanges of driving-belt when intersecting guiding wherein.Intersection guiding by driving-belt guarantees that driving-belt not only needn't extend but also needn't shrink, and therefore can adopt a driving-belt along the forward motion direction rigidity.The such driving-belt of tensioning one and allow the form of implementation of the rigidity of device of the present invention to heavens.
For the fiber of sensitivity is not coming in contact with the part of each motion when a multi-axial fabric is overlapping, set driving-belt and exist one to cross the live-roller on each angle of coiling plate or the small plussage of guide roller.In method of the present invention and device of the present invention, be used as in each angle of plate on coiling plane four vertically disposed live-rollers and/or guide roller are being set.They roughly at the center by means of a fringing in a bearing.The plussage that driving-belt is crossed the width of live-roller and/or guide roller causes crossing fringing and bearing and carries fiber via the driving-belt tensioning, and the contacting of part of fiber and these motions do not taken place.The size of plussage must be chosen to make the machinery that may exist to be arranged in the size of plussage at this in order to rabbet live-roller and/or guide roller.Intersection guiding by driving-belt reaches, and driving-belt needs in height to reverse with respect to the outside dimension on each side at the center of coiling plate lessly, but for this reason need bigger reversing on width.The guiding that reduces highly here for very sensitive fiber is important prerequisite, so that it does not come in contact with the part of each motion or the each several part that is not different from pace with its speed.
Set in of the present invention one favourable form of implementation, use a moulding driving-belt, it has at least one projection to the drive side of moulding driving-belt.Reach by described at least one moulding projection on the drive side of a moulding driving-belt, making can be around live-roller and/or guide roller guiding driving-belt, wherein by reverse in case of necessity can be on each roller generation power, it causes that driving-belt slides from live-roller and/or guide roller.If each format roll definitely is not parallel to each other and distinguishes in pairs at a plane interior orientation, then can produce these power.Therefore the moulding driving-belt compensates the small orientation error of live-roller and/or guide roller.
In particularly advantageous form of implementation of the present invention, the moulding driving-belt has the moulding projection that a plurality of sensings drive the side, thereby can powerful ground tensioning driving-belt, and do not stay the shearing force of so high side because of big tension force at this on each moulding projection, so that the too early wearing and tearing of driving-belt take place.Live-roller and/or guide roller have a recessed shape corresponding to the moulding driving-belt under the situation that adopts the moulding driving-belt, thereby live-roller and/or guide roller hold vertical moulding of driving-belt reliably and therefore guide driving-belt.
In another favourable form of implementation of the present invention, the moulding driving-belt has an additional tooth portion, does not drive driving-belt thereby can reliably have by tooth portion slidingly.
In order to reel plane and be used for single shaft and can rotate mutually to the storage device of fabric, this external of the present invention one favourable form of implementation is set, driving-belt has a forming part on outside, comprise that these recesses have the order of magnitude corresponding width of the width of one and one fiber transverse to many moulding recesses of the rotation direction extension of driving-belt.Guarantee that thus the fiber of reeling is in the meticulous moulding recess on the outside of driving-belt and is not easy to intersect mutually because of the small asynchronous movement of driving-belt and storage device or twisted on the coiling plate, because meticulous moulding recess keeps fiber at preposition.
Set in the method for the invention, adopt a plurality of idler rollers, it is perpendicular to live-roller and/or guide roller is directed and its orientation setting transverse to driving-belt.These idler rollers preferably are in the center on coiling plane or near its center, each driving-belt part mutual plane ground intersects there.Stop each driving-belt part may be absorbed in and cause thus too early wearing and tearing mutually because of vibration in case of necessity and grind away by each idler roller.In this setting, each idler roller not only influences the stroke of driving-belt in the inside of the capacity on coiling plane, and set, each idler roller should the tensioning driving-belt, so that driving-belt is not easy to tight waist when reeling, wherein fiber has the less diameter that needs than the top layer coiling that is two live-rollers and/or guide roller and therefore may tear when pulling out from the coiling plane when reeling around the coiling plane.
For the securable property setting of the raising of driving-belt, driving-belt has a steel band, and it constitutes driving-belt along the special rigidity of the forward motion direction.Whereby can powerful ground tensioning driving-belt, thus driving-belt is not easy to a tight waist when reeling with carbon fiber, so not high as the tension force of fruit fiber, thus the elasticity of steel band produces the words of the tight waist of driving-belt between two live-rollers and/or guide roller.Definitely at this essential be, driving-belt must have a steel band, and the driving-belt that also might adopt a usefulness fabric to strengthen, wherein except that disposing natural fiber, also can adopt carbon fiber or
Fiber.
In another form of implementation of method of the present invention on the coiling plane and below on the surface of an arch is set, it covers driving-belt the inside on coiling plane.By the intersection guiding that also might abandon driving-belt.Also might be on the surface that arch is set on each side and on the coiling plane and below on be equipped with the driving-belt of motion, thereby bigger surface does not have frictionally and multi-axial fabric is carried with small friction in each side.
The invention still further relates to a kind of method that is used to make by fiber, the multi-axial fabric that particularly constitutes by carbon fiber, wherein with a unidirectional webs at angle around a coiled sheet coiled one yarn volume, wherein plate is provided with one in order to pull out the yarn volume in the device of friction compensation and the slave plate.
The purpose of this invention is, a kind of method is provided, and it can pull out the yarn volume that is made of fiber from a plate, thereby forms the even multi-axial fabric of shaping by two planes.
Reach purpose of the present invention by using a cascade guider, this cascade guider is arranged on the terminal of plate and has the wedge that stretch out a side.Draw other favourable form of implementation of the present invention by all dependent claims.
Cascade guider of the present invention has a wedge as main member on the end of plate, its end that columnar yarn is twisted in plate is converted into a smooth folding web that is made of two planes, and wherein winding board is reeled a single shaft respectively to fabric.Wedge has a special geometry at this, and it causes yarn is rolled up the distortion that is converted into multi-axial fabric equably and does not form each edge of webs.The bottom surface of wedge this have one be same as plate cross section geometry and be set directly on the plate.But according to an existence that is used to reduce the device of friction onboard one spacing is set, so as in case of necessity below wedge guiding by the part of each motion.The interarea that two of plate deviates from each other, that is plate top and enlarged in echelon below by wedge.On the contrary, each side of plate connects by the wedge triangularity with a last thickness, and leg-of-mutton bottom surface has the width that fabric is stretched out plate in the side as the identical width of the thickness of plate and triangle.What be arranged on plate top and following trapezoidally has a bottom surface, and it meets width of fabric, and the small size of wherein undercutting width of fabric is not so that be subjected to mechanical stress to guide fabric on wedge.
In a special form of implementation of cascade guider of the present invention, wedge has a lug boss endways, that is joins in two trapezoidal positions and its bottom surfaces, and the advantage of lug boss is, pulls out the yarn volume that almost is stacked into a flat web from wedge equably.
In another favourable form of implementation of the present invention, wedge has a little projection on the top of side, and wedge seamlessly transfers a projection on each edge of lug boss, so that reduce the frictional resistance of fiber on the lateral edges of lug boss.
Be chosen to make its thickness at this width than the accurately wide coiling plate of width of coiling plate with two of wedge trapezoidal bottom surfaces.One small dimensional tolerance lower limit also is set in this respect, can be subjected to the landing from the wedge of stress ground so that make around volume.
In concrete form of implementation of the present invention, wedge in the cascade guider, have one be same as plate cross section the bottom surface and end by the tetrahedroid at each edge that protrudes in plate in the plane of plate in the side is set.The width of two planes of each the trapezoidal extension plate that protracts mutually by wedge and two trapezoidal bottom surfaces increases the thickness of plate with respect to the width of plate whereby.The length of wedge is matched with the mobile performance of yarn volume.Yarn volume flowable is big more, then wedge must select long more so that when yarn volume is configured as the fabric on a plane, stop the small skew that occurs on each fiber each edge and guarantee the uniformity of the multiaxial contexture web made like this thus with small as far as possible consequence at the coiling plate.
Except that wedge, also have a plurality of rollers at another form of implementation cascade guider of the present invention, on wedge, guide the yarn volume around it.Therefore the form of implementation of method of the present invention is characterised in that and uses each roller in the cascade guider, and it is with the speed drive of fabric, thereby each roller is neither braked and do not driven fabric and fabric is pressed onto on the wedge.Each roller is controlled by means of sensor in an advantageous manner, thus therefore when each roller is not braked fabric and pull out the yarn volume in slave plate still the pressed yarn volume draw back mutually by forward travel.Because each fabric is stable with respect to the distortion of each web unlike a yarn fabric and along a plurality of directions, importantly, each hold-down roller just is pressed onto fabric on the wedge about forward travel and braking in the ideal case feebly, forms distortion so that avoid pulling out yarn when volume in slave plate at the yarn volume in the forming process of a fabric.
In favourable form of implementation of the present invention, adopt at least two roller arrangements, it has a plurality of rollers that are provided with respectively on a common axle, and wherein different roller arrangements has the speed of the different speed that is matched with the yarn volume of pulling out.Have the small different direction of motion at the yarn volume in the forming process of a uniform fabric in web, its forward motion direction about fabric has the durection component of pointing out from web in the side.These durection components may form different sizes in different positions.Therefore proved advantageously, do not adopted straight-through roller at the cascade guider, proof advantageously adopts each roller that is matched with the local velocity of web respectively, and they are arranged on the shaft device.Avoid whereby, form because the inhomogeneities that roller speed occurs the coupling of one of the yarn volume average forward travel speed, it can cause the distortion in multiaxial contexture web.Adopt at least two roller arrangements in an advantageous manner, it is provided with in succession and according to the length of wedge it is added, thereby the whole surface of yarn volume along wedge is pressed onto on the wedge equably.
In another favourable form of implementation of the present invention, in the cascade guider, adopt at least two roller arrangements, it has a plurality of rollers that are provided with respectively on a common axle, it is directed that wherein different roller arrangements has the axle of the different flow directions that is matched with the yarn volume of pulling out.Each roller of the yarn volume being pressed to wedge not only suffers the different speed of yarn volume at the yarn volume in the forming process of a multiaxial contexture web, but also will pass through different flow directions.At the center of plate, flow direction and web direction are uniformly set.On each side of wedge, each vertical side of the plate of reeling there extends into triangle and centers on the edge guiding of the wedge that stretches out the side, and the component of yarn volume has a small different flow direction.Reach by this form of implementation of the present invention, each roller mates according to flow direction, and it is owing to distortion produces.Avoid whereby, roll up in the forming process that is configured as webs at yarn and in multiaxial contexture web, may form distortion.
Proved that advantageously at the terminal upper edge of wedge lug boss traction fabric, it is arranged on the end of wedge and has the very little shape of wall thickness of an essentially rectangular.Provide fabric to be oriented in possibility on the lug boss whereby, and do not need a support that supports is formed distortion at this.
Set for the friction that reduces on the edge of lug boss, each edge is equipped with the projection of a small formation, projection is constituted fiber can be laid around projection, and is not torn.The bending property that depends on the fiber that in fabric, adopts in this protruding profile widely.Flowing and set when being shaped in order to help yarn to twist in, wedge is a slightly rounded on each edge, and for to carry out the transition to lug boss to fluidly from wedge, each tip of wedge ends at a little projection, it seamlessly transfers the projection of lug boss to.
Proved advantageously that at this projection is dwindled minutely gradually to the end of lug boss.When pulling out, reduce gradually around the coiling stress of the machinery of lug boss by diminishing projection.Can select or increase ground, the geometry of lug boss also can be slightly trapezoidal, thereby lug boss dwindles gradually to the width of the end that takes out the yarn volume that is shaped from lug boss with respect to wedge.Dwindling portion by this also realizes being reduced in and pulls out the yarn mechanical stress in when volume.
In special form of implementation of the present invention, each part of cascade guider is provided with a surface that reduces to rub.Having proved particularly advantageous in this respect is the surface that constitutes of the polymer by a poly-fluorine and to have proved more particularly advantageous be the surface that the material with carbon element by the diamond class constitutes, and it has more especially little friction than carbon fiber.Avoid forming frictional force thus, it causes uneven shaping and therefore produces inhomogeneities in the yarn volume that is shaped.
The invention still further relates to a kind of in order to make the method for a multi-axial fabric that preferably constitutes by carbon fibre material, wherein the single shaft of at least one storage device is reeled around a coiling plane to fabric, reel this moment plane and described at least one storage device rotates mutually, so that yarn coiling plane coiling single shaft is to fabric, and one in order to implement the corresponding device thereof of method of the present invention.
The objective of the invention is in addition, a kind of method and a kind of its corresponding device that is used to make multi-axial fabric is provided, it overcomes shortcoming of the prior art.
Reach this purpose according to the present invention by using an oscillation drive, it is in the mechanical oscillation coiling plane.By drawing other favourable form of implementation of the present invention in all dependent claims.
In the method that is used for making a multi-axial fabric, from one preferably with unwinding one single shaft on the storage device of a roll form to fabric and reel around a coiling plane at angle.For this reason reel plane and described at least one storage device rotates mutually, thereby the single shaft of storage device is reeled around the coiling plane to fabric.In order from the coiling plane, to pull out the fabric of coiling, set according to the present invention, adopt an oscillation drive, it is in the mechanical oscillation coiling plane.Vibration has small amplitude and higher frequency at this.Set in a preferred form of implementation at this, the curve of determining in the time plot of position is followed in the vibration of the direction that is parallel to each lateral edges that produces by vibration, carries each fiber along a preferred orientations whereby.Also might implement vibration along other direction about the lateral edges on coiling plane.Do not apply mechanical oscillation if there is preferred orientations, then in the most of the time, be not in directly and contact, because it is pushed open from the coiling plane because of mechanical oscillation with the coiling plane around the fiber of coiling flat formation.Might be in the time of this weak point to pull out fabric in the small frictional resistance slave plate.Be not that whole fibers take away from the coiling plane at one time at this be unessential, therefore reduce average friction significantly by vibration.If opposite enforcement is parallel to the vibration of each side on coiling plane, then might carry each fiber of webs with a preferred orientations by the mode of a vibration guiding of determining.If make winding station be in vibration with high frequency, little amplitude and the definite preferred orientations of nothing, then can be to pull out fabric in the small resistance slave plate.If opposite with frequency match in the friction of fabric on the coiling plane, then by moving through the frictional resistance conveying fiber slowly and transferring the frictional resistance of adhesion friction to a sliding friction along pull-out direction by a setback fast, this moment, the inertia of fiber stoped the sliding apace backrush of fiber on the plane, then carried fabric along preferred orientations.By mechanical oscillation along pull-out direction and the conveying that reaches fiber along two of direction of retreat different speed.Travel forward lentamente on coiling plane when pull-out direction vibrates.This slowly in the motion process fiber be on the surface on coiling plane with adhesion friction and therefore move forward by plate.Fiber forwards the sliding friction state to from an adhesion friction state when the setback fast on coiling plane, and move below fiber backward on the plane of reeling this moment, and fiber is not followed this setback.Be fed forward whole fabric in such a way equably.To oscillation drive advantageously, though the fabric friction on the coiling plane is inevitably carried fabric via the coiling plane, and be not easy to intersect and can make in such a way a uniform fabric at this each fiber.
Therefore possible, produce the state of the low friction of fabric on the coiling plane and might have the vibration that produces an orientation along the directional vibration of the different speed of different direction of vibration by one by a nondirectional vibration, it causes along the preferred orientations conveying fiber.Directed vibration is applicable to that such being used to make the method and apparatus of a multi-axial fabric, wherein pulls out multi-axial fabric from the coiling plane.The vibration of opposite orientation is applicable to such method and apparatus, does not wherein pull out multi-axial fabric or do not derive from the coiling plane by gravity from the coiling plane by another device, and make the fabric forward travel by vibration.
Favourable mode with method of the present invention adopts an oscillation drive, and its generation has about the mechanical oscillation of zigzag characteristic basically of position time plot.This oscillating movement in the time plot of position the steeper flank of tooth against the direction orientation of the pull-out direction of fabric oscillating movement in the time plot of position the not too steep flank of tooth to the direction orientation of the pull-out direction of fabric.Reach the conveying of fiber on the coiling plane in an advantageous manner by this zigzag characteristic, thereby can avoid another to be used to pull out the device of fabric about the position time plot.
In order to regulate the frictional resistance of fiber on the coiling plane, might make the coiling plane stand a delicate tissuesization.Can reach the frictional resistance determined of fiber on fabric by delicate tissuesization, thereby can regulate amplitude and vibration frequency whereby, for example might regulate the vibration with less frequency and less amplitude whereby, it is essential for travelling forward uniformly of each fiber.By less amplitude and less frequency, have significantly low wearing and tearing structure, be possible and in order to make the coiling plane be in vibration, device needs a spot of energy in order to the device of implementing method of the present invention.Might be chosen to make the resonant frequency on coiling plane accurately corresponding to being used for the weight and the elasticity on coiling plane in addition in the required frequency of the conveying fiber on coiling plane.Those skilled in the art can freely regulate the frequency that is used for microscopic structureization, weight, elasticity, vibration and the important parameters of amplitude in this by experiment.
In favourable form of implementation of the present invention, the forward travel speed of the fiber of fabric on the coiling plane is synchronous around the relative rotation speed on coiling plane by oscillation drive and storage device.Make during the relative revolution half-turn on coiling plane the tangent of fabric forward travel winding angle α multiply by the product of the width on coiling plane at this at storage device, wherein α measures between the orientation of the fiber of fabric at the orientation and the single shaft of the lateral edges on coiling plane.Carry out continuous winding process with storage device around the relative rotating synchronous realization on coiling plane by forward travel speed, webs constitutes multi-axial fabric and does not form a coiling linear slit in winding process.
Because the coiling plane has a last thickness, what become necessity in this case is to change forward travel speed by oscillation drive in winding process.In winding process, pass through two different edge patterns with respect to turning round the tensioning single shaft to fiber.One time single shaft passes through an edge tensioning to fiber in a process that revolution 1/4th is enclosed relatively, so that single shaft to the fiber of fabric be laid in the coiling plane one above and below one on, and once single shaft to fabric the process of relative revolution 1/4th circle in by an edge tensioning fiber, so that single shaft is on the fiber of fabric is laid in the narrow lateral edges on coiling plane.Forward travel is synchronous all the time and does not form the coiling linear slit whereby, and therefore necessary is to make forward travel synchronous to the different tensioning state of the fiber of fabric with single shaft by oscillation drive.This upward or below when reeling than when reel in the side on coiling plane, regulating oscillation drive quickly at fiber.Therefore in the process that turn around change forward travel speed at described at least one storage device around returning relatively of coiling plane by oscillation drive.When single shaft to the fiber of fabric by the coiling plane the lateral edges tensioning and when being wound up on the surface on coiling plane, the product of the width on the coiling plane that the per quart of forward travel speeds match in the tangent of winding angle α and coiling plane changes, wherein α measures between the orientation of the fiber of fabric at the orientation and the single shaft of the lateral edges on coiling plane.On the contrary when single shaft to the fiber of fabric by a lateral edges tensioning on coiling plane and when on a lateral edges on coiling plane, reeling, the product of the thickness on the coiling plane that the per quart of forward travel speeds match in coiling tangent of an angle and coiling plane changes, wherein winding angle is measured between the orientation of the fiber of fabric at the orientation and the single shaft of the lateral edges on coiling plane.
In the advantageous manner of method of the present invention, vibration frequency is chosen as 1Hz to 500Hz, preferred 2Hz to 100Hz, preferred especially 3Hz to 50Hz, and very preferred 5Hz to 50Hz.
Advantageously amplitude is chosen as simultaneously 0.001cm to 10cm, preferred 0.01cm to 5cm, preferred especially 0.1cm to 1cm and more preferred 0.2cm to 0.5cm.
