Preparation method of carbon fiber-reinforced silicon carbide brake disc
The invention relates to a preparation method of a carbon fiber-reinforced silicon carbide brake disc, belonging to the technical field of brake materials. The preparation method comprises the following steps: firstly, carrying out heat treatment on short carbon fibers, then uniformly mixing the short carbon fibers having mixed lengths with resin and an additive, putting the mixture into a molding press for molding, then carrying out high-temperature cracking in a nitrogen or inert gas protective atmosphere, and finally, carrying out silicon infiltration in a vacuum infiltration furnace to obtain the carbon fiber-reinforced silicon carbide brake disc. According to the method, the short carbon fibers with mixed lengths are adopted as a raw material and subjected to mold pressing, cracking and infiltration in a solid environment to prepare the brake disc; and the method is simple, a period is short, the raw material is wide in source and low in cost, and the prepared carbon-ceramic brake disc has excellent performance and has good market application prospects.
本发明涉及一种碳纤维增强碳化硅刹车盘的制备方法，属于刹车制动材料技术领域。先将短切碳纤维进行热处理，然后将混合长度的短切碳纤维与树脂以及添加剂混合均匀后放入模压机中模压，再在氮气或惰性气体保护气氛下进行高温裂解，最后在真空熔渗炉中进行硅熔渗，得到碳纤维增强碳化硅刹车盘。本发明所述方法采用混合长度的短切碳纤维为原料，在固态环境下通过模压、裂解、熔渗制备出刹车盘，方法简单、周期短、原料来源广泛、成本低，而且制备出的碳陶刹车盘有着优异的性能，具有很好的市场应用前景。
