When expecting part, diversion pipe can leave very deep impression at the back side of product, so that influencing product quality.The prior art product with
The phenomenon that upper plastic board of pad between diversion pipe, plastic board can mitigate impression to a certain extent, but plastic board hinders tree
The flowing of rouge in a mold, leads to product starved, influences product quality.
Summary of the invention
For the prior art, there are above-mentioned technical problems, and it is an object of that present invention to provide a kind of vacuum to import manufacture carbon fiber
The method that composite material eliminates diversion pipe impression, this method has the advantages that easily operated.
For achieving the above object, the following technical schemes are provided:
A kind of method that vacuum imports manufacture carbon fibre composite elimination diversion pipe impression, includes the following steps,
1) die treatment: cleaning mold is simultaneously thoroughly dry by it, release agent is then coated in mold cavity, release agent is dry
Coat gel coat again afterwards；
2) it is laid with surface felt: in gel coat surface glue spraying, then sticking layer of surface felt and compacting surface felt；
3) layers of reinforcement and release cloth are laid with: being successively laid with layers of reinforcement and release cloth on the felt of surface, and
The layers of reinforcement and the demoulding layer of cloth are successively compacted；
4) it is laid with porous material layer: being laid with porous material layer on release cloth, the porous material layer is uniform on release cloth
Distribution, is then laid with diversion pipe, the tube wall of the diversion pipe offers several water conservancy diversion gaps, described on the porous material layer
Water conservancy diversion gap is connected with the hole body of the porous material layer；
5) it is laid with vacuum bag: entire mold is sealed using vacuum bag and seal the surface felt being laid on mold, enhancing
Then material layer, release cloth, porous material layer and diversion pipe vacuumize the vacuum bag, check the air-tightness of the vacuum bag,
Make the equal attaching and compacting of material in entire mold；
6) resin and demoulding and diversion pipe are imported: importing resin from diversion pipe, resin is flowed out from diversion pipe and passed through more
Hole body in Porous materials layer is to flow into mold, after resin solidification, successively sloughs vacuum bag, diversion pipe, porous material layer and de-
Mould cloth, demoulding obtains product.
Wherein, the water conservancy diversion gap is spirally coiled on the diversion pipe.
Wherein, the diameter diameter of the porous material layer side length vertical with the diversion pipe length direction and the diversion pipe
The ratio between long is 5~8:1.
Wherein, the porous material layer is successively stacked by several layer unit porous material layers and is constituted.
Wherein, the edge of each layer unit porous material layer is encapsulated together using edge banding machine fixed to constitute porous material
Layer.
Wherein, the edge of each layer unit porous material layer is tied up together using ventilative bandage to constitute porous material
Layer.
Wherein, the void density of the porous material layer is 150/m2, and the aperture of the hole body is 0.5~0.6cm.
Wherein, the material of the porous material layer is elastic material.
Beneficial effects of the present invention:
Porous material layer is increased between release cloth and diversion pipe, which can effectively disperse diversion pipe pressure
Pressure on product avoids the problem of diversion pipe impression is left on product, which is bonded with release cloth, so that
The pressure of porous material layer is dispersed on product, also avoids porous material layer the problem of leaving impression on product；And
Since the water conservancy diversion gap of diversion pipe side is connected with the hole body in porous material layer, the resin in diversion pipe passes through porous material layer
In hole body can swimmingly be transmitted in mold, ensure that the quality of product.
