Preparation method of high-strength and high-toughness silicon carbide nanowire reinforced silicon carbide ceramic composite material
The invention relates to a preparation method of a high-strength and high-toughness silicon carbide nanowire reinforced silicon carbide ceramic composite material . The preparation method comprises the following steps of: preparing a silane coupling agent modified silicon carbide nanowire, preparing a phenolic resin coating coated silicon carbide nanowire, preparing a carbon coating coated siliconcarbide nanowire, and preparing the silicon carbide nanowire reinforced silicon carbide ceramic composite material. According to the method, effective transfer of loads between the silicon carbide ceramic matrix and the nanowire reinforcement is guaranteed, and the carbon coating on the surface of the silicon carbide nanowire can effectively protect the silicon carbide nanowire in the silicon carbide nanowire from being damaged due to reaction with the matrix during high-temperature sintering.
本发明涉及一种高强度高韧性的碳化硅纳米线增强碳化硅陶瓷复合材料的制备方法，包括：硅烷偶联剂改性碳化硅纳米线制备，酚醛树脂涂层包覆的碳化硅纳米线制备，碳涂层包覆的碳化硅纳米线制备，碳化硅纳米线增强碳化硅陶瓷复合材料制备。该方法保证碳化硅陶瓷基体与纳米线增强体之间载荷的有效传递，且碳化硅纳米线表面的碳涂层可以有效保护其内部的碳化硅纳米线在高温烧结时不因与基体发生反应而破坏。
