Description

A kind of many beam box section co-curing shapings of composite make frock and making with enhancement layer Technique
Technical field
The invention belongs to composite autoclave forming process technical field, in particular it relates to a kind of many beams of composite Box section co-curing shaping makes frock with enhancement layer, and using the technique of the making frock making enhancement layer.
Background technology
Autoclave (Hot Air Autoelave write a Chinese character in simplified form Atitoelave) be it is a kind of for polymer matrix composite into The process equipment of type process characteristic, the method for moulding process is carried out autoclave molding method using this equipment.Autoclave molding Method is the main method for manufacturing continuous lod same with thermosetting compound material product, is now widely used for advanced composite material knot The shaping of structure, honeycomb sandwich construction and metal or adhesive bonding of composites structure.When material is molded, offer simultaneously in autoclave is utilized Uniform temperature and well-distributed pressure and solidify, complex-shaped so it is high to can obtain surface and internal soundness, huge compound of area Material.
Autoclave molding method is one of widely used process both at home and abroad at present, be mainly used in large scale, profile compared with The manufacture of complicated Aeronautics and Astronautics FRP components, such as Skin Parts, beam, frame, various wallboard parts, floor and radome fairing.Autoclave into The general principle of type method is:Prepreg is laid on mould by laying requirement, and be put into autoclave after being sealed in vacuum bag In, by the heating of autoclave equipment, pressurization, material solidification reaction is completed, prepreg blank is turned into required shape and is met matter Measure the process of desired component.
Carbon fiber enhancement resin base composite material has specific strength and specific modulus is high and designability is strong and is easy to overall The advantages such as shaping, therefore be widely used in aviation field, especially in terms of civil aircraft.Composites Molding Techniques are very Many, prepreg-autoclave technique, in occupation of critical positions, there is co-curing with its excellent product quality, cementing altogether, secondary cementing Etc. mode.
The composite torsion-box structural member at home and abroad employed in army's civil aircraft project generally uses following several sides at present Formula is manufactured:
1st, after composite material skin and beam part are separately fabricated by assembly connection into box section;
2nd, RTM techniques;
3rd, rubber pneumatic bag moulding process.
In three of the above process, the 1st kind of method is using splicing frock, the covering and beam part positioning error of box section Greatly, it is impossible to ensure depth of beam and the up and down depth of parallelism of covering, and the manufacturing cycle is long, cost is big.2nd kind of method and the 3rd kind of side Method is overall co-curing shaping, although shortens the cycle, reduces cost, but can not ensure the Forming Quality of part.2nd kind Method requires very high to Resin Flow, may be only available for specific resin system, and the product resin gel content being molded compared with It is high and unstable, it is impossible to be used in the load box section structure of aircraft.3rd kind of method uses rubber pneumatic bag expandable pressurized, due to air bag In die cavity, cause the temperature homogeneity of whole product and mould poor, and there is ageing of rubber, swell increment dyscalculia etc. to ask Topic, easily causes pressurization inequality, so as to cause the problems such as position skew, flexural deformation, overall box section quality cannot be ensured.
The content of the invention
It is an object of the invention to:For prior art Forming Quality it is poor the problem of there is provided a kind of many beams of composite Box section co-curing shaping makes frock and manufacture craft with enhancement layer;The enhancement layer makes frock and manufacture craft existing many Secondary solidification is reassembled on the basis of technique, is improved the intensity of part, can be ensured Forming Quality.
To achieve these goals, the technical solution adopted by the present invention is:
A kind of making frock of many beam box section co-curing shaping enhancement layers of composite, including enhancement layer are made in frock Die body and enhancement layer make frock lower mold body, and both include coplanar side, and the side is angled with enhancement layer institute is On-right angle.
The weak link of part is typically that the setting of enhancement layer improves the part of junction in the junction of beam and covering Thickness, improves the shaping strength of part.If by prepreg by sideline be right angle in the way of set, its be molded zero Part, is easily deformed in beam with covering contact position, thus it is in oblique angle mode that enhancement layer sideline, which is set, then can avoid out Existing above mentioned problem.Because prepreg is very soft and frivolous so that the operation for cutting oblique angle in its side becomes very difficult.This Enhancement layer prepreg is clamped between two die bodys by the making frock of invention, and prepreg is extended to outside die body, in two die bodys Side be provided with inclined-plane, then two die bodys will presoak material clamping it is close after, you can carry out cutting operation.
Preferably, the enhancement layer makes frock upper die body and enhancement layer makes frock lower mold body and is halfpace Shape, and the homonymy inclined-plane difference of two halfpaces is coplanar.Prepreg is held between the two by upper halfpace with lower halfpace, utilizes halfpace two The coplanar inclined-plane in side, can once cut into the enhancement layer shape finally needed.
Further, during the two ends that the enhancement layer making frock upper die body and enhancement layer make frock lower mold body are portrayed Line.The setting of center line is more accurately cut, and is more convenient operation.
Utilize the work of the making frock making enhancement layer of the above-mentioned many beam box section co-curing shaping enhancement layers of composite Skill, comprises the following steps:
F1, on a table top upper berth enhancement layer prepreg is folded, surplus is left in the both sides of the enhancement layer prepreg;
F2, enhancement layer prepreg is placed on to the enhancement layer makes frock upper die body and enhancement layer makes frock lower mold body Between, and clamping makes both inclined-planes coplanar;
F3, with knife close to enhancement layer make frock upper die body and enhancement layer and make the inclined-plane of frock lower mold body and cut out reinforcement The oblique angle of layer prepreg;
F4, the enhancement layer made is placed between covering blank and beam blank.
By said modules and step, enhancement layer of the side with oblique angle can be produced, enhancement layer is mated formation in beam blank Between covering blank, three in one co-curing is molded, the Forming Quality of part is improved.
Preferably, the surplus in the step F1 is 10-20mm.
Preferably, the step of also being alignd in the step F2 including center line:Enhancement layer is made into frock upper die body The center line positioned in alignment of frock lower mold body is made with enhancement layer.The setting of center line is more accurately cut, and is more convenient operation.
In summary, by adopting the above-described technical solution, the present invention is relative to the beneficial effect of prior art:
1st, the present invention has ensured the shaping strength of part central sill and covering junction, further ensures the shaping matter of part Amount.
2nd, present invention process is simple to operate, and repeatability is strong.
