Ceramic matrix composite connecting fastener and preparation method thereof
The invention discloses a ceramic matrix composite connecting fastener and a preparation method thereof. The ceramic matrix composite connecting fastener comprises a fixing part and a connecting part, the upper end of the fixing part is connected with the lower end of the connecting part; the fixing part comprises a fixing part cavity, a fixing part connecting layer and a fixing part base body which are sequentially arranged from outside to inside; therefore, the problems that the ceramic-based composite material connecting fastener is broken and damaged when the temperature is greatly changed and the ceramic-based composite material connecting fastener is easy to oxidize, embrittle and damage when the temperature is 800-1000 DEG C for a long time are solved; therefore, the carbon fiber reinforced silicon carbide ceramic matrix composite connecting fastener can be used for a long time under a wide temperature range service condition.
本发明公开一种陶瓷基复合材料连接紧固件及其制备方法，陶瓷基复合材料连接紧固件包括固定部和连接部；所述固定部的上端与所述连接部的下端连接；所述固定部包括自外而内依次设置的固定部腔体、固定部连接层和固定部基体；从而解决了陶瓷基复合材料连接紧固件在温度发生极大变化时出现断裂损坏问题以及解决了温度长时间处于800～1000℃时陶瓷基复合材料连接紧固件容易氧化变脆易损坏的问题，从而实现碳纤维增强碳化硅陶瓷基复合材料连接紧固件在宽温域服役条件下长时间使用。
