Abstract
The invention relates to carbon fiber cloth, and a gluing method for a carbon fiber composite material composed of the carbon fiber cloth. The carbon fiber cloth is formed by staggering a plurality of carbon fiber beams according to the texture angles of 0 DEG, -20 DEG, 20 DEG,-45 DEG and 45 DEG; then the carbon fiber cloth is paved in a lapping, folding and overlapping manner, and is demoulded and cured. The carbon fiber cloth adopts particular texture angles, and adopts the lapping, folding and overlapping manner, so that the composite materials in all layers are more tightly glued, bubbles have the low probability of generation during hot-forming, stress is balanced, and performance of the product is improved.
Description
Technical field
The present invention relates to a kind of hot press forming technology technical field of composite, the applying method of carbon fibre composite particularly relating to a kind of carbon cloth and be made up of it.
Background technology
The hot press forming technology of carbon fiber composite material article is: after being heated by processing mold, preformed carbon fibre composite is put into mould cavity, with pressure, mould is fixed on heating plate, control melt temperature and the time of resin, melt after-hardening, cooling to reach, then taken out model finished product.Usually, before hot-forming, be all the multi-storey up-down and translation of definite shape size is superposed and is laid on the model designed, the demoulding, then carry out hot-forming.There is following technical problem in above-mentioned technique: 1, is directly superposed by multi-storey up-down and translation, and laminating is not tight, has bubble, causes properties of product to decline; What 2, hot press forming technology adopted is the mode that segmentation spreads cloth, and centre resin carries out bonding, through the impact of excess pressure, easily produces bubble, causes the easy failure fracture in junction; The textile board angle of carbon cloth 3, used is: 0 °, ± 30 °, 90 °, and this frame mode is after shock-testing, compression test, testing fatigue and vibration-testing, and result shows: this kind of angle stress dispersion is uneven, easily causes fracture.
Summary of the invention
The object of the invention is to the defect overcoming above-mentioned prior art, provide a kind of intensity high, the felt properties of cloth is good, and then makes cloth surrounding stress distribution even, the carbon cloth of stress equalization;
Another object of the present invention is to provide one makes each layer composite fit more closely, not easily produces bubble, stress equalization, and then the applying method of the carbon fibre composite be made up of above-mentioned carbon cloth of effectively enhancing product performance.
The technical scheme taked for realizing object of the present invention is:
A kind of carbon cloth, is characterized in that this carbon cloth is formed according to the texture angle of 0o, ± 20o, ± 45o is staggered by several carbon fiber bundles.
Described carbon cloth thickness is 0.08 ~ 0.12mm.
An applying method for the carbon fibre composite be made up of above-mentioned carbon cloth, is characterized in that its technique comprises: adopt the mode overlapping also coincidence of a folding to carry out laying, the demoulding afterwards carbon cloth, solidification.
Described overlap joint in coincidence of a folding process, the overlap distance between each layer is 10mm, the center-line joint place thickness after folding is 10mm.
Described solidification adopts hot press to realize, controlled pressure 10kg/cm
2, temperature: 150 DEG C-200 DEG C, time: every 10-15cm
2mould need time 30-35 minute.
Technical advantage of the present invention is embodied in:
1, the carbon cloth that the present invention is used is formed so that the texture angle of 0o, ± 20o, ± 45o is staggered by several carbon fiber bundles, wherein: 0o yarn can the rigidity of reinforcement carbon fiber wire; 20o can increase the hot strength of carbon fiber wire; 45o can reinforcement sheared edge, increases carbon fiber wire anti-torsional strength; The carbon cloth that this three kinds of angles are staggered into, through repeatedly putting into practice trial-production, intensity is high, is not easily torn, falls silk, and the felt properties of cloth is good, so the stress distribution of living surrounding orientation is even, stress equalization.
2, the present invention is in laminating process, adopts the mode of laminating limit, limit heating that resin is softened, ensure that each layer is fitted more closely.
3, the present invention adopts overlap joint the mode of coincidence of a folding carries out superposition laying from bottom to top, maintains smooth, the uniform force everywhere of whole composite, thus prevents the generation of bubble.
In sum, the present invention can make each layer composite fit more closely, not easily produces bubble, everywhere stress equalization, thus improve properties of product time hot-forming.

Detailed description of the invention
Below in conjunction with example, the specific embodiment of the present invention is elaborated.It should be understood that example is for illustration of the present invention instead of limitation of the present invention.Scope of the present invention and core content are determined according to claims.
1, mould is designed according to product size.
2, according to the size of die size design carbon cloth, reserve and cut type point (namely the cutting position of amounting to, contributes to product size more accurate).
Carbon cloth resin used and carbon fiber form through infiltrating then to solidify.This carbon cloth forms stagger angle by several carbon fiber bundles according to 0o, ± 20o, ± 45o, and a branch of interlocking forms.0o yarn can the rigidity of reinforcement carbon fiber wire; 20o can increase the hot strength of carbon fiber wire; 45o can reinforcement sheared edge, increases carbon fiber wire anti-torsional strength; The carbon cloth that this three kinds of angles are staggered into, through repeatedly putting into practice trial-production, intensity is high, is not easily torn, falls silk, and the felt properties of cloth is good, so the stress distribution of living surrounding orientation is even, stress equalization.
3, according to the number of plies of the good carbon cloth of the size design of product.Often opening carbon cloth thickness is 0.08 ~ 0.12mm.
4, by the carbon cloth cut according to type of the cutting point reserved, expand to both sides from centre, and heat with laminating limit, blowing hot wind equipment limit, make resin soften, more fit tightly.
5, for preventing the generation of bubble, laying adopts the mode of overlap joint coincidence of a folding, to the thickness needed for product.Be specially, adopt and expanded to both sides by middle body frame from top to bottom, from left to right, symmetrical.Overlap distance between each layer is 10mm, and the center-line joint place thickness after folding is 10mm.Can keep that whole composite is smooth, uniform force everywhere like this, and prevent bubble from therefrom producing.
6, after laying, i.e. the demoulding, is put into hot press, utilizes its pressure and high temperature to make resin solidification, pressure: 10kg/cm
2(area of finger print tool), temperature: 150 DEG C-200 DEG C, time: according to the difference of mould size, every 10-15cm
2mould need time 30-35 minute, fit tightly between each layer of cloth, formed product.
