Manufacturing process for carbon-carbon composite material flat plate
The invention discloses a manufacturing process for a carbon-carbon composite material flat plate. The manufacturing process comprises the following steps: chopping carbon fiber tows, combing, lappingand needling the carbon fiber tows into net tyres, cutting and spreading the net tyres according to a product dimension; weighing certain weight of chopped fiber tows by an electronic scale, and uniformly dispersing the weighed fiber tows to the spread net tyres; covering a layer of net tyres on the surfaces of the dispersed tows, introducing Z-direction fibers by a flat plate needling machine, continuously dispersing the carbon fiber tows, covering the net tyres, needling, and repeating the processes until a product reaches a designed thickness, thereby accomplishing manufacturing of carbonfiber prefab; infiltrating the carbon fiber prefab with resin, hot-pressing, curing and forming through a hot press, and performing carbonization, densification and high-temperature treatment on a hot-pressed, cured and formed carbon fiber resin plate to manufacture a carbon-carbon composite material plate. Unit layers consist of the chopped fibers and the net tyres, and are compounded into an integer through needling.
本发明公开了一种碳碳复合材料平板的制备工艺，将碳纤维丝束短切丝，然后经梳理、铺网、针刺成网胎，并将网胎按产品尺寸裁切，铺平；用电子秤称取一定重量的短切纤维束；然后将称好重量的纤维束均匀地分散在平铺的网胎上；然后在撒好的丝束表面再覆盖一层网胎，通过平板针刺机，引入Z向纤维，然后继续分散碳纤维丝束，然后覆盖网胎，针刺，重复这一过程，直至产品达到设计厚度，即完成碳纤维预制体的制作；然后浸润树脂，经热压机热压固化成型，将热压固化成型的碳纤维树脂板经炭化、增密、高温处理，制成的碳碳复合材料板材；本发明的单元层由短切纤维和网胎组成，然后通过针刺复合成整体。
