Carbon-carbon or carbon-ceramic composite material short fiber preform and product and preparation method thereof
The invention relates to a carbon-carbon or carbon-ceramic composite material short fiber preform and a product and a preparation method thereof, and is characterized in that the core of the preparation method is that short carbon fibers are extruded and molded through an extruder to realize a continuous molded product; the short carbon fiber preform is obtained by adopting the preparation method; and the carbon-carbon or carbon-ceramic composite material product is obtained by vapor deposition or liquid deposition or a combination method of the vapor deposition and the liquid deposition. The invention has the beneficial effects that the raw material cost is low, the preparation method is simple in process, continuous production can be realized, the production efficiency is high, the product can be directly formed according to the shape of a final product, the machining allowance is reduced, the grinding waste is reduced, the preparation period is greatly shortened, and the cost is reduced; and an annular slitting process is adopted, so that edge materials and core materials do not need to be removed, and the waste of the carbon-carbon composite material brake disc preform material can be reduced.
本发明涉及碳碳或碳陶复合材料短纤预制体及其制品以及制备方法，其特征在于，其制备方法核心在于将短切碳纤维通过挤出机挤出成型，实现连续性的成型产物；采用上述制备方法获得的一种短切碳纤维预制体；以及经过气相沉积或液相沉积或两者组合方法获得碳碳或碳陶复合材料制品。本发明的有益效果在于：利用纯短纤维制成短切碳纤维复合材料制品、原料成本低、其制备方法工艺简单、可以连续生产，生产效率高、可以直接按照最终产品外形成型，减少加工余量，减少磨削浪费、大大缩短制备周期，减少成本；采用环形分切工艺，无需去除边料和芯料，可以使得碳碳复合材料刹车盘预制体材料的浪费减少。
