Repairing agent and method for repairing surface of carbon-based composite material
The invention provides a repairing agent. The repairing agent is prepared from one of phosphoric acid and phosphate, a curing agent and nano ceramic powder. The invention further provides a method for repairing the surface of the carbon-based composite material. The repairing agent provided by the invention takes phosphoric acid or phosphate as a matrix, copper oxide as a curing agent and ceramic powder as filler; in a high-temperature service environment, oxides in the repairing agent can react with carbon atoms diffused from a carbon base to generate carbide ceramics, so that the oxidation resistance and cohesiveness of the carbon-based composite material are further improved; and the repairing agent can be cured at normal temperature after a curing agent is added, the dependence on equipment is greatly reduced, and the repairing agent plays a very important role in simply repairing the surface of the carbon-based composite material large-size special-shaped part.
本发明提供了一种修补剂，由磷酸和磷酸盐中的一种、固化剂和纳米陶瓷粉组成。本申请还提供了一种碳基复合材料表面修补的方法。本申请提供的修补剂以磷酸或磷酸盐为基体、氧化铜作为固化剂、陶瓷粉体作为填料；在高温服役环境下，修补剂内部的氧化物会与碳基扩散出来的碳原子反应生成碳化物陶瓷，进一步提高了碳基复合材料的抗氧化性和粘结性；修补剂可在加入固化剂后常温下固化，大大降低了对设备的依赖性，对于碳基复合材料大尺寸异型件表面的简单修补具有非常重要的作用。
