S2, carbon fibre material are immersed in solution, then carry out the laying of prepreg.
S3, pre-suction adhesive process are sucked out certain under conditions of certain temperature and pressure from carbon fibre material layer laminate block The resin of amount, so that the resin content of layer of carbon fiber material is controlled.
S4, pyrocondensation technique, in the case where heated, the resin in layer of carbon fiber material can soften, while thermal contraction plastic expects pipe Layer can be shunk in the case where heated, and thermal contractible plastic tube layer, which is shunk, to apply pressure to layer of carbon fiber material, so that the tree of flowing Rouge levelling in the case where pressure.
S5, cure process after heat-shrink tube contraction, continue to increase temperature, resin is in higher temperatures in hot-press equipment Start to solidify under the conditions of degree, so that the shape that the generation between layer of carbon fiber material is fixed, while can be with during cured Air molecule existing between carbon fibre material is removed using layer of auxiliary material.
S6, releasing process, during cured, thermal contractible plastic tube layer softens into rubbery elastic in the event of high temperatures Body can be demoulded directly by the first separation layer and the second separation layer, and the process generation of demoulding is avoided to be adhered.
As a kind of preferred embodiment of the invention, first separation layer and the second separation layer are non-silicon demoulding Oxidant layer.
As a kind of preferred embodiment of the invention, the layer of auxiliary material is vacuum bag.
As a kind of preferred embodiment of the invention, the hot-pressing thermal that the curing process uses is standby for autoclave.
As a kind of preferred embodiment of the invention, the mold is column steel die.
As a kind of preferred embodiment of the invention, the predip solution is vinylbenzyl alkyd resin solution.
Compared with prior art, beneficial effects of the present invention are as follows:
1. carbon fiber tubular member forming method of the invention is shunk under conditions of high temperature, together automatically by thermal contractible plastic tube layer When layer of carbon fiber material resin softens in the event of high temperatures, pyrocondensation institute's plastic pipe layer shrink layer of carbon fiber material is carried out it is equal Even pressure, so that resin levelling, achievees the effect that keep article surface smooth.
2. carbon fiber tubular member forming method of the invention, is provided with the first separation layer and carbon by the outer surface of mold Fibrous material layer surface is provided with the second separation layer, so that avoiding the occurrence of being convenient in demoulding after hardening and being adhered phenomenon, influences to give birth to The qualification rate and efficiency of production.
3. carbon fiber tubular member forming method of the invention is vacuum bag by layer of auxiliary material, so that in cured mistake It is capable of providing vacuum state in journey, the air molecule of institute's band in material is taken away, avoids solidifying the influence by air.
Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, other feature of the invention, Objects and advantages will become more apparent upon:
Fig. 1 is pyrocondensation schematic diagram in the embodiment of the present invention.
In figure: 1 mold, 2 first separation layers, 3 layer of carbon fiber material, 4 second separation layers, 5 thermal contractible plastic tube layer, 6 auxiliary Material layer.
Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to Specific embodiment, the present invention is further explained.
Referring to Fig. 1, the present invention provides a kind of technical solution: a kind of carbon fiber tubular member forming method: the carbon fiber Tubular member molding includes the following steps are as follows:
The pre-processing of S1, thermal contractible plastic tube layer, 5 surfaces externally and internally of thermal contractible plastic tube layer carry out coating the second separation layer 3 and The first separation layer 2 of coating is carried out on 1 surface of mold.
S2, carbon fibre material are immersed in solution, then carry out the laying of prepreg.
S3, pre-suction adhesive process are sucked out one from 3 lamination block of layer of carbon fiber material under conditions of certain temperature and pressure Quantitative resin avoids the excessive subsequent technique of content from needing to increase suction so that the resin content of layer of carbon fiber material 3 is controlled Glue material causes trouble.
S4, pyrocondensation technique, in the case where heated, the resin in layer of carbon fiber material can soften, while thermal contraction plastic expects pipe Layer 5 can be shunk in the case where heated, and thermal contractible plastic tube layer 5, which is shunk, to apply pressure to layer of carbon fiber material, so that flowing Resin levelling in the case where pressure, so that pipe profile surface after molding is smooth.
S5, cure process after heat-shrink tube contraction, continue to increase temperature, resin is in higher temperatures in hot-press equipment Start to solidify under the conditions of degree, so that the shape that the generation between layer of carbon fiber material 3 is fixed, while can be with during cured Air molecule existing between carbon fibre material is removed using layer of auxiliary material 6, air molecule is avoided to cause solidification It influences.
S6, releasing process, during cured, thermal contractible plastic tube layer 5 softens into rubbery state bullet in the event of high temperatures Property body, can directly be demoulded by the first separation layer 2 and the second separation layer 4, avoid demoulding process generation be adhered.
In the present embodiment, the first separation layer 2 and the second separation layer 4 are non-silicon releasing agent layer, and layer of auxiliary material 6 is true Empty bag, the hot-pressing thermal that curing process uses is standby for autoclave, and mold 1 is column steel die, and predip solution is poly- for vinylbenzyl Rouge resin solution.
In conclusion temperature needed for pre-suction adhesive process, pyrocondensation technique and cure process in the present invention, so that logical It crosses layer of carbon fiber material 3 and different thermal contractible plastic tube material determines, inhale adhesive process and need stationary temperature, in technical process In can directly be demoulded by the first separation layer 2 and the second 4 layers of isolation, avoid the process generation of demoulding from being adhered, Er Qiere Contracting technique makes pressure uniform, so that softening resin can be driven plain, avoids material surface appearance after molding rough Phenomenon is produced by the technique, so that qualification rate and efficiency can be promoted effectively.
