一种制造复合材料空心帽材的方法

本发明提供的一种制造复合材料空心帽材的方法，主要包括：制备块状树脂制膜；细化固化温度、固化时间、固化压力和固化施加点；将没有浸渍树脂的纤维缝编套预制件在所述阳模上预成型帽材；将帽材连同阳模(即芯模)封装在内真空袋与阴模之间，并将它们一同封装在外设真空袋内，形成内外袋封装结构，然后施加真空压，在加热和加压的作用下，树脂膜熔融渗透浸渍到帽材纤维缝编物的纤维间，使树脂成膜状。其中在制造复合材料空心帽材加筋结构件中，采用渗透预定型和固化两步完成和树脂膜采用模板真空压制，以及模具结构采用阳模和阴模结合的方法。避免了芯模无法从固化后帽材中取出，阴模成型脱模难的问题。且树脂渗透完全，含量均匀。树脂与纤维结合紧密。

Method of manufacturing composite-material hollow capmaterial

The invention provides a method of manufacturing a composite-materialhollow cap material. The method mainly includes steps of: preparing blockyresin into a film state; refining curing temperature, curing time, curingpressure and curing application point; pre-forming a cap material on a male dieby using a fiber stitch-bonded sleeve preform which is not impregnated inresin; packaging the cap material together with the male die (i.e., a core die)between an inner vacuum bag and a female die, and packaging all the parts in anexternal vacuum bag to form an inner/outer bag packaging structure; applyingvacuum pressure, so that the resin film is molten in and permeates to aposition between the fibers in the cap material fiber stitch-bonded preformunder the actions of heating and pressurizing so that the resin forms a film.During manufacturing of a ribbing structure member of the composite-materialhollow cap material, two steps of permeation pre-shaping and curing areemployed and the resin film is formed by vacuum compression with a mold plate.The mold is in a structure of combination of a male die and a female die, sothat a problem that the core die cannot be removed from the cured cap materialand a problem of difficulty of shaping and demolding of the female die are avoided.The resin is complete in permeation and is uniform in content, and is tightly combinedwith the fibers.
