Modified carbon fiber hard felt as well as preparation method and application thereof
The invention provides a modified carbon fiber hard felt as well as a preparation method and application thereof. The modified carbon fiber hard felt comprises carbon fibers, and silicon carbide and carbon which are compounded on the carbon fibers. The modifier is adopted to modify the carbon fibers, polymethylphenylsiloxane in the modifier serves as a main material and can form a silicon carbide ceramic membrane through subsequent high temperature, the silicon carbide ceramic membrane is compounded on the surfaces of the carbon fibers, and the silicon carbide ceramic membrane can enhance the surface hardness and oxidation resistance of the carbon fibers; the wear resistance and the high-temperature resistance of the carbon fiber are improved, so that the service life of the carbon fiber in a vacuum high-temperature furnace is prolonged. In addition, the carbon nanotubes in the modifier can further enhance the mechanical properties of the carbon fibers.
本发明提供了一种改性碳纤维硬毡及其制备方法与应用。所述改性碳纤维硬毡包括碳纤维和复合在所述碳纤维上的碳化硅和碳。本发明通过采用改性剂对碳纤维进行改性处理，所述改性剂中的聚甲基苯基硅氧烷作为主要材料，经过后续的高温可形成碳化硅陶瓷膜，复合在碳纤维表面，所述碳化硅陶瓷膜可以增强碳纤维的表面硬度和抗氧化性能，提高碳纤维的耐磨性和耐高温性能，从而延长其在真空高温炉中的使用寿命。另外，改性剂中的碳纳米管可以进一步增强碳纤维的力学性能。
