提出了一种C/SiC复合材料的连接方法:在线气相穿刺连接。该方法是在C/SiC复合材料制备的最后一步——SiC沉积过程中,对待连接件进行C纤维束穿刺,穿刺后继续沉积SiC,最终在完成复合材料制备的同时,结束复合材料的连接过程。采用该方法,对2D和3DC/SiC复合材料进行了在线气相穿刺连接。结果表明:在线气相穿刺连接所得接头热物理和热化学相容性好,连接应力低,拉伸强度可达82MPa,连接过程不影响构件的使用温度,是一种适合于纤维增韧陶瓷基复合材料的连接方法。 A C / SiC composite connection method is proposed: online gas-phase puncture connection. In the final step of C / SiC composite preparation - during the deposition of SiC, the connector is subjected to C-fiber bundle puncturing, followed by deposition of SiC after puncturing, and finally the composite material connection is completed while the preparation of the composite material is completed . Using this method, 2D and 3DC / SiC composites were connected by gas-phase puncture. The results show that the joints obtained by on-line gas phase puncture have good thermophysical and thermochemical compatibility, low connection stress and tensile strength up to 82MPa. The connection process does not affect the service temperature of the components. It is a suitable composite for fiber-toughened ceramic matrix Material connection method.
