SiC nanowire toughened PyC/SiC composite interface of SiCf/SiC composite material and preparation method of SiC nanowire toughened PyC/SiC composite interface
The invention belongs to the field of material preparation, and particularly relates to a SiC nanowire toughened PyC/SiC composite interface of a SiCf/SiC composite material and a preparation method of the SiC nanowire toughened PyC/SiC composite interface. According to the technical scheme, a PyC/SiC composite interface is toughened through SiC nanowires of the SiCf/SiC composite material, a PyC interface layer, the SiC nanowires and a SiC interface layer are sequentially deposited on the surface of a SiC fiber preform through a chemical vapor infiltration technology, and a composite interface between ceramic fibers and a matrix is formed. According to the SiC nanowire toughened PyC/SiC composite interface of the SiCf/SiC composite material and the preparation method of the SiC nanowire toughened PyC/SiC composite interface, the toughness and oxidation resistance of a ceramic composite material can be improved, and meanwhile, the brittleness of the interface is improved.
本发明属于材料制备领域，具体涉及一种SiCf/SiC复合材料的SiC纳米线增韧PyC/SiC复合界面及其制备方法。本发明的技术方案如下：SiCf/SiC复合材料的SiC纳米线增韧PyC/SiC复合界面，通过化学气相渗透工艺在SiC纤维预制体表面依次沉积PyC界面层、SiC纳米线和SiC界面层，形成陶瓷纤维与基体间的复合界面。本发明提供的SiCf/SiC复合材料的SiC纳米线增韧PyC/SiC复合界面及其制备方法，能够提升陶瓷复材的韧性及抗氧化性能且同时改善界面脆性。
