Definitions

  • the invention relates to a fiber composite material including fibers and a resin connecting the fibers. Additionally, the invention relates to a method for producing a fiber composite material including fibers and a resin connecting the fibers.
  • Fiber composite materials are multi-phase or mix materials which include a bedding matrix made from resin and reinforcing fibers. Through interaction of the two components a fiber composite material has better properties than the fibers or the resin respectively by themselves.
  • the so-called effect of specific strength influences the fiber composite material in a positive manner.
  • a reason for this effect is the increasing alignment of the molecule chains of the fibers for a reduced diameter in the decreasing cross-sectional surface that is provided.
  • the plurality of extremely thin fibers also leads to a distribution of the fracture inducing voids in the material to very large distances.
  • fiber composite materials are characterized by excellent properties which are achieved through optimum interaction of both components. In particular fiber composite materials have a very good ratio of strength to weight.
  • fibers for fiber composite materials typically glass fiber, carbon fibers, ceramic fibers (aluminum oxide, silicon dioxide, etc.), aramide fibers, metal fibers, in particular steel fibers and natural fibers (from flax, hemp, jute, sisal, etc.) are being used.
  • the resin matrix of the known fiber composite materials is typically formed by duromeres (synonyms: duroplast, synthetic resin) elastomeres or thermoplasts.
  • Laminates in which the advantages of an individual fiber orientation are being used.
  • Laminates often include a plurality of fiber mats that are placed on top of one another with different main fiber orientations.
  • typically methods like manual placement, manual placement with vacuum pressing, prepreg technology, vacuum infusion, fiber winding and fiber spraying are being used, wherein the latter strictly speaking is not a laminating method since there are no defined layers, whereas the result however has comparable properties like classic laminates.
  • fiber composite materials are often also implemented in the form of injection molded components, injection pressed components and extruded components, wherein the unidirectional orientation of the fibers can be practiced with different degrees of success depending on the method.
  • SMC sheet molding compounds
  • a frequent disadvantage of fiber composite material is the incomplete embedding of fibers into the resin matrix. This occurs typically when subsequently infusing composite structures made from fibers (woven materials, laid tapes, knitted material, fleeces, etc.) and applies in particular for a processing of the fiber monofilaments into threads when using a twisting or threading of monofilaments.
  • the intermediary cavities between the individual filaments can hardly be completely reached or filled considering the viscosity of the resin so that the strength of the materials obtained remains significantly below the theoretically possible amount.
  • the portion of the resin relative to the mass or the volume of the entire fiber composite material from a cost point of view and from energy and environmental points of view is too high.
  • a fiber composite material which includes threads which include a plurality of individual filaments and resin that is crosslinkable through the effect of at least one physical variable and/or at least one chemical material, wherein the resin in a non-crosslinked condition is provided essentially free from solvents and the plurality of individual filaments in the thread is cohesive, wherein the individual filaments in the threads are arranged unidirectionally and wherein the threads thus form a composite material in that they adhere to one another at contact surfaces of their respective outer enveloping surfaces through bridges made from resin.
  • the fiber composite material according to the invention described supra is a semi-finished product since the resin is provided in non-crosslinked condition in which it only has a minor portion of its final strength or hardness and in this intermediary state of the composite material is only used to keep the composite material formed from threads together in order to make it fit to handle at all.
  • the fiber composite material according to the invention is thus characterized by good deformability and flexibility, so that it still can be formed before crosslinking, this means that it can be brought into its final form before the actual crosslinking, this means hardening of the resin occurs in order to produce a finished product from the semi-finishes product, wherein the finished product can certainly be processed further in additional process steps.
  • the monofilament threads used for producing composite materials according to the invention include a plurality of individual filaments and resin enveloping the individual filaments.
  • the unidirectionally aligned individual filaments in the threads thus constructed are preferably completely embedded by the resin, wherein no air enclosures shall be in the resin anymore.
  • the individual filaments are joined by the resin to form a thread that can be handled as a monofilament, the individual fibers, however, are movable relative to one another with respect to their positions. This is important in particular when adjacent threads of the composite material formed from threads can flatten their cross-sections at their contact locations, thus forming greater contact surfaces than this is the case for threads Which include twisted individual filaments.
  • the size of the contact surfaces substantially determines the subsequent strength of the fiber composite material after curing the resin.
  • the material according to the invention is the fact that no additional resin has to be used when forming the composite material. Thus, the process of infusing, submerging, spraying, pouring, etc. of a support structure formed from fibers as required for conventional production methods is omitted.
  • the resin portion for the fiber composite material according to the invention is very small, since the resin is only used where it adheres to the threads or their individual filaments.
  • the resin portion in case this is desired, can be increased through adding more resin that is independent from the threads, for example, to fill the cavities that typically otherwise remain between the threads.
  • the important advantages of the fiber composite material provided through the invention thus are large contact surfaces at the contact points of the threads due to their capability to still deform also after production of the intermediate product “fiber composite material with non-crosslinked resin” while maintaining the sub-composite “thread”, wherein typically the cross-section of the thread is theoretically deformable from a circular flattened shape to a rectangular shape.
  • the line shaped contact portions for geometrically exactly circular threads and parallel alignment of adjacent threads rectangular contact strips are formed for the material according to the invention, whose surface is accordingly larger which yields better cohesion, this means higher strength of the finished product in crosslinked condition.
  • fiber composite material is provided in non-linked condition in order to retain many degrees of freedom for the subsequent use and to let only the subsequent user decide which particular geometric shape the fiber composite material shall assume.
  • the resin is only crosslinked when the material is brought into the desired shape, for example, through bending, pressing, rolling, winding, stretching, laminating, etc.
  • threads adhering to one another can be pressed against one another, wherein preferably the composite material as such is being pressed.
  • the applied pressure should be moderate and only serve the purpose to couple the threads to one another at their surfaces through bridges of the non-crosslinked resin.
  • the actual curing process of the resin (and if required, another pressing process) is then typically performed at another location at another point in time after the fiber composite material with the non-cured resin is brought into its final shape through additional processing, in particular forming.
  • the fiber composite material is a knitted material, a laid material, a fleece or a woven material, preferably with linen binding which includes warp threads and/or filling threads which form a monofilament composite, including a plurality of individual filaments and the non-crosslinked resin, wherein the individual filaments of all recited threads are aligned unidirectionally relative to one another. Based on the large contact surfaces between the threads, a material with excellent strength properties can be provided this way.
  • the fiber composite material is a sandwich material including at least one layer including a woven material, preferably with linen binding and at least one layer including a fleece, wherein the woven material includes threads, preferably only includes threads which include a plurality of individual filaments and the non-crosslinked resin and the fleece is provided with a non-crosslinked resin, in particular infused therewith or sprayed therewith, and the layers are connected with one another through bridges from resin between adjacent threads of adjacent layers in order to form the fiber composite material.
  • the object is furthermore achieved through a composite material which includes threads which include a plurality of individual filaments and which include the crosslinked resin which connects the individual filaments with one another, wherein the individual filaments are arranged unidirectional relative to one another, so that the threads form an interconnection, wherein the contact surfaces of the outer enveloping surfaces of the threads are connected with one another through bridges of the crosslinked resin.
  • the material described supra compared to the other material described supra is also a fiber composite material according to the invention, thus a finished product since the resin is provided in crosslinked condition, this means in cured condition.
  • the composite material has reached its final hardness and can be handled with considerably less care than the material described supra with the non-crosslinked resin.
  • the fiber composite material according to the invention with crosslinked resin is therefore particularly suitable for standard products like plates or profiles with various cross-sections, tubes, etc. which are produced in standardized dimensions and are traded and stocked like standard semi-finished products. Also a use as support woven material or laid support material or other types of textile fabrics or also grids is possible.
  • the strength and the manufacturing method the same applies as stated supra regarding the composite material with non-crosslinked resin.
  • the cross sections of the threads are oval, ellipsoid or rectangular with rounded corners at least in the portion of their contact surfaces, wherein the contact surfaces in the cross-section are at the flattened sides of the oval or of the ellipse or at the long sides of the rectangle.
  • the contact surfaces in the cross-section are at the flattened sides of the oval or of the ellipse or at the long sides of the rectangle.
  • the composite material according to the invention can be a sandwich material, preferably including at least one layer including a woven material, a laid material, a knitted material, etc. and at least one layer including a fleece, wherein the woven material, the laid material or the knitted material includes threads according to the invention with individual filaments in unidirectional orientation with embedded resin.
  • the provided sandwich material can be formed through pressing into a formed component or a profile, in particular a I-, L-, T-, U-, V-, H- or Y-profile and can be crosslinked during pressing or subsequently, in particular through heat impact.
  • the solution according to the invention furthermore includes a method for producing a fiber composite material including fibers and a resin crosslinking the fibers comprising the following steps:
  • a) threads are being used for the fiber composite material which respectively include a monofilament composite including a plurality of individual filaments which are kept together through a resin that is crosslinkable under an impact of at least one physical variable and/or a chemical substance, wherein the individual filaments of a thread are respectively aligned unidirectional;
  • a composite material is formed from the threads in that adjacent threads are connected with one another at contact surfaces of their outer enveloping surfaces through bridges of a resin provided in non-crosslinked condition, wherein the connecting resin previously formed a portion of the threads.
  • the method according to the invention thus uses particular monofilament threads whose individual filaments are movable relative to one another due to the resin not yet being crosslinked, so that the cross-sectional shape of the threads can still be changed under impact of external forces.
  • the non-crosslinked resin is provided in a condition due to storing capabilities and further processing capabilities in which it essentially does not include any more solvent. However, it has a “residual tackiness” which facilitates coupling resin encased threads through contacting them so that the composite thus formed can be handled, this means can be stored, wound, stacked, packaged, etc. without the resin previously already having to be transformed into the crosslinked condition.
  • the adjacent threads that are respectively connected with one another through a resin bridge can be pressed into one another in the portion of the contact surface. Imparting pressure thus causes a change of the shape of the thread cross-section in the sense of a flattening and thus an increase of the surfaces that are in contact with one another.
  • Forming the interconnection from threads with non-crosslinked resin according to the method according to the invention is thus provided independently from the crosslinking of the resin and thus from achieving the final strength of the fiber composite material.
  • pressing the threads together in the interconnection previously formed and crosslinking in particular under the impact of temperature is at least partially performed simultaneously.
  • the manufacturing method is particularly efficient.
  • a tubular hollow profile with circular, oval, elliptical or polygonal cross-section is produced from the threads including the non-crosslinked resin embedding their monofilaments and the hollow profile is subsequently formed through longitudinally progressing contraction in a direction perpendicular to the longitudinal axis of the hollow profile to form a profile with reduced cross-sectional surface, preferably using pressure orthogonal to the longitudinal axis of the hollow profile and wherein the resin is crosslinked during forming or subsequent thereto in particular through heat application.

  • the individual filaments 2 of a first type which are arranged in a substantially circular inner zone 4 of the cross-section of the thread 1 include, for example, para-aramide, however the individual filaments 3 of the second type which are arranged in an annular outer zone 5 about the inner zone 4 and form a type of “jacket” are made from glass fibers about the “core” formed by the inner zone 4 .
  • All known fibers are suitable as individual filaments for the fiber composite material according to the invention, in particular the fibers already recited supra. Certainly also only one single type of individual filaments can be arranged in a thread.

  • the particular threads 1 for example, have a configuration according to FIGS. 1 and 2 , but can also be configured differently.
  • the resin which keeps the individual filaments 2 , 3 of the threads 1 together is provided in non-crosslinked condition, so that the cohesion of the thread 1 which is considered as a monofilament is provided, however relative movability of the individual filaments 2 , 3 is still provided as long as the resin is not cured, this means not crosslinked.
  • the individual filaments 2 , 3 of the threads 1 are all oriented unidirectionally, this means they extend parallel to one another and parallel to a longitudinal axis of the thread 1 .
  • This alignment of the individual filaments 2 , 3 has to be maintained during windup of the threads 1 after their production, but also during the entire subsequent production process of the linen woven material of the fiber composite material 8 (weaving process). For this reason, it is not possible to use the so-called “overhead pull off” for threads from spools that is otherwise widely used in the production of woven materials.
  • it is important that the individual filaments 2 , 3 of the threads 1 are also all still unidirectionally aligned in the linen woven material according to FIG. 3 .

  • the threads are only lightly changed in any cross-sectional shape, this means flattened, so that the contact surfaces 12 a in the portion of the intersecting threads 1 are comparatively small, namely the width of a strip shaped contact surface 12 a is much smaller than the diameter of the thread 1 .
  • a bridge 13 a is configured from non-crosslinked resin which connects the threads 1 that are crossing over, this means in particular the individual filaments 3 of the respective outer zone 5 provided in the threads 1 , with one another.

  • the layers 16 of the woven material are arranged rotated in an alternating manner by 45° with reference to the longitudinal direction, for example, of a group of threads (filling threads).
  • the thickness 19 of a single layer 16 of woven material is between 0.35 mm and 1.5 mm
  • the thickness of a layer 17 made from fleece with approximately 0.15 and 0.25 mm is much smaller than the recited material .thickness.
  • the nineteen individual layers of fiber composite material 18 illustrated in FIG. 5 in non-pressed condition have a thickness 21 of 0.45 to 1.7 mm.
  • the fiber composite material 18 is pressed together, for example, with a plate press and thus in a direction of the arrow 22 which yields a reduction of the thickness 23 provided after the pressing and curing process.
  • FIG. 6 illustrates in a schematic depiction how the production process of an additional alternative embodiment of a fiber composite material 28 configured as an L-profile in cross-section can be provided.
  • a starting point for the eventually L-shaped profile as illustrated in FIG. 6 in the right half of the figure is a profile 24 with a cross-section shaped like a circular ring drawn in the left half of the figure in solid lines.
  • the latter profile is produced using a mandrel, whose outer diameter corresponds to an inner diameter 25 of the profile cross-section in that the threads 1 are applied to an outer enveloping surface of the mandrel e.g. in cross-binding.
  • the threads 1 used for this purpose in turn include a plurality of individual filaments of the same type or of various types of individual filaments in mixed or spatially separate arrangement and a non-crosslinked resin enclosing the threads which provides monofilament properties to the thread. It is furthermore important for the winding process that it does not introduce any twist into the thread, this means also in wound form all individual filaments of all threads have unidirectional orientation.
  • a cohesion of the particular threads in the wound composite is provided through selecting a suitable winding tension which provides a sufficiently strong contact for threads crossing over one another in the portions of their contact surfaces (c.f. illustration of threads crossing over one another according to FIG. 4 a ).
  • the contact surfaces at which bridges with non-crosslinked resin are formed are still comparatively small, so that the winding compound provided in tubular form has sufficient cohesion for handling, but no strength which would be required for a use as a finished material.
  • a wall thickness 26 of the wound tube is approximately between 0.45 mm and 2.4 mm. Depending on the diameter of the used threads, approximately 2 to 60 thread layers are required for achieving a wall thickness in this range. It is also important in this case that when producing the wound composite contrary to classic procedure when producing fiber composite material, no additional resin is used to close the gaps remaining between the particular threads.
  • layers made from a resin infused fleece including different fibers can also be arranged between adjacent thread layers during winding in order to create a denser material with a larger surface area so that e.g. the damping and insulating properties are improved.
  • the semi-finished product configured as a tubular profile 24 can be pulled off from the support mandrel. Since the resin in this instant is not crosslinked, the profile 24 has comparatively large flexibility and deformability, so that its shape can be changed within wide ranges under the impact of internal forces. Thus, for example, a pressure can be imparted upon the profile 24 , for example, in the direction of the arrow 27 through a suitable tool, e.g.
  • the profile 24 in its intermediary condition can have the shape with an indented cross-section according to the dashed lines 30 in the left half of FIG. 6 .
  • the L-profile 31 is provided as a result, which is depicted in FIG. 6 on the right.
  • This is an L-profile with arms with identical lengths, wherein both L-arms have a contact surface 33 in their centers, at which sections of the prior inner enveloping surface 34 of the profile 24 join due to the pressing process.
  • the inner contact surface 33 is not visible in the finished profile 31 .
  • the inner contact surface is not relevant with respect to the material and strength properties since due to the high pressure also in this portion of the contact surfaces 33 , a flattening of the threads coming in contact with one another occurs, so that the contact surfaces between the threads and the bridges formed by the resin are accordingly large which as a result creates a component with very homogeneous properties over the entire profile cross-section.
  • the length of the profiles thus produced can be up to 10 m or more.
  • the material properties are significantly influenced by the amount of the pressure which is applied after producing a thread composite, wherein the pressure is still applied using the resin in non-crosslinked condition.
  • the flattening of the threads and thus the size of the contact surfaces and also of the resin bridges increases which yields higher strength and density of the material but also reduced elasticity.
  • materials can also be produced with a higher elasticity in cured resin condition and also with greater porosity, this means with greater surface area, which is important in particular for insulation and absorption properties.
  • the specific weight of the fiber composite material according to the invention can be varied through selecting a suitable pressure within a rather large range.
  • Another aspect of the invention is using a pulp, for example, an aramide pulp in order to be able to obtain a filling or reduction of the cavities of the loops 9 of a woven material with a grid structure according to FIG. 3 without using a fleece.
  • a comparatively open woven material as illustrated in FIG. 3 can be pulled through a bath, for example, at an angle between 15° and 45° relative to one of the thread systems, wherein the bath includes a mix of water, resin and high fiber content pulp (surface approximately 13 m 2 per gram of fibers).
  • additives in the form of micro-balloons made from glass or porous balls made from ceramic or solid balls made from ceramic or spherical particles made from molten aluminum silicate or kaolin can be added.
  • the woven material or its threads absorb different amounts of pulp.
  • the pulp which is preferably highly loaded with fibers causes mechanical interlocking of the threads of the grid shaped woven material.
  • Producing a fiber composite material of this type is similar to producing paper, wherein the grid shaped woven material is used as a component that remains in the finished fiber composite material as a solid component later on.
  • the resin provided in the threads of the tissue (c.f. FIG. 3 ) is not crosslinked at the point in time of immersion in the pulp bath and is dissolved again through the solvent included in the pulp bath and is thus very receptive for high fiber content pulp so that the adhesion effect is very good.
  • a slight compression of the composite thus provided and a drying preferably through an air flow dryer can be performed at temperatures below 120° C. in order to prevent crosslinking the resin also in this case.
  • a second press process can occur in which in turn the temperature has to be kept at a low level (30° C. at the most).
  • a woven material made from the same fibers or from other fibers can be applied in order to subsequently cause an application of the fibers forming the pulp through a movement through the pulp bath.
  • a Teflon coated grid can be used as tool when applying the pulp fibers, wherein the grid is removed again after the drying process.
  • the process of producing a fiber composite material of this type can also be performed as a flow process like paper production.
  • the grid woven material is moved through the pulp bath in order to achieve fiber adhesion.
  • Removing the solvent of the pulp bath from the fiber composite material being created can be performed through vacuum suction boxes.
  • the solvent content can be reduced through pressing between rollers analogous to the pressing portion of a paper machine.
