Preparation method of carbon fiber reinforced SiC-SiBC (N/O) composite material
The invention belongs to the technical field of ceramic preparation, and relates to a preparation method of a carbon fiber reinforced SiC-SiBC (N/O) composite material. According to the preparation method of the carbon fiber reinforced SiC-SiBC (N/O) composite material, provided by the invention, a boron-containing ceramic precursor and a SiC ceramic precursor are used for sequentially or alternately carrying out impregnation-cracking on a carbon fiber preform, the boron content and boron-containing phase distribution in the composite material are regulated and controlled, and the obtained composite material has excellent mechanical properties and a self-healing function.
本发明属于陶瓷制备技术领域，涉及一种碳纤维增强SiC‑SiBC(N/O)复合材料的制备方法。本发明提供的碳纤维增强SiC‑SiBC(N/O)复合材料的制备方法以含硼陶瓷先驱体、SiC陶瓷先驱体先后或者交替对碳纤维预制体进行浸渍‑裂解步骤，调控复合材料中的硼含量和含硼相分布，得到的复合材料具有优异的力学性能和自愈合功能。
