Carbon nanotube/fiber multi-scale reinforced ceramic matrix composite material and preparation method thereof
The invention discloses a carbon nanotube/fiber multi-scale reinforced ceramic-based composite material and a preparation method thereof.The preparation method comprises the steps that firstly, a catalyst is evenly loaded on the surfaces of fibers through an impregnation method, then a polycarbosilane precursor is subjected to high-temperature pyrolysis to generate reducing gas and carbon source gas needed by growth of carbon nanotubes, growth of the carbon nanotubes in fiber fabric is completed, and the carbon nanotube/fiber multi-scale reinforced ceramic-based composite material is obtained. The carbon nano tube/fiber reinforced fabric is obtained, and the carbon nano tube/fiber reinforced ceramic matrix composite material can be obtained after the carbon nano tube/fiber reinforced fabric is subjected to densification treatment. The preparation process is simple, the process of providing the reducing gas and the carbon source gas by the polycarbosilane precursor is safe and controllable, and the method has remarkable advantages in the aspect of rapid and safe preparation.
本发明公开了一种碳纳米管/纤维多尺度增强陶瓷基复合材料及其制备方法，首先采用浸渍法使催化剂均匀负载于纤维表面，再使聚碳硅烷前驱体高温裂解生成碳纳米管生长所需还原气体和碳源气体，完成碳纳米管在纤维织物中的生长，得到碳纳米管/纤维增强体织物，对碳纳米管/纤维增强体织物进行致密化处理后，即可得到碳纳米管/纤维增强陶瓷基复合材料。本发明制备工艺简单，聚碳硅烷前驱体提供还原气体和碳源气体的过程安全可控，在快速安全制备方面具有显著优势。
