摘要

连续碳纤维增韧碳化硅陶瓷基复合材料的机械连接技术是推动该复合材料应用于航空航天复杂热结构件的关键。本文采用化学气相渗透工艺制备了M5 3DN C/SiC螺栓和螺母，系统研究了其在室温、300 ℃、600 ℃、1000℃的拉伸性能，并基于微结构演变分析了其高温拉伸退化机理。结果表明，3DN C/SiC 复合材料的孔隙主要出现在三维针刺层周边和无纬布层中，加工过程中切削力变化造成了螺纹缺齿。M5 3DN C/SiC螺栓的高温拉伸失效模式主要有螺柱拉断和螺牙拉脱两种。1000 ℃拉伸位移为1/2螺距时，由于发生基体开裂并随着载荷增加出现裂纹扩展，裂纹处裸露的碳纤维受到1000 ℃高温氧化环境影响，其后续的承载能力快速丢失。

Abstract

Mechanical joining technology for continuous carbon fiber reinforced silicon carbide ceramic matrix composites is key to promoting the application of this composite material in complex thermal structural components in the aerospace field. This study employed the chemical vapor infiltration process to fabricate M5 3DN C/SiC bolts and nuts

systematically investigating their tensile properties at room temperature

300 ℃

600 ℃

and 1000 ℃. The high-temperature tensile degradation mechanism was analyzed based on microstructural evolution. The results indicate that pores in the 3DN C/SiC composite primarily occur around the three-dimensional needled layers and within the unidirectional cloth layers.Variations in cutting forces during the machining process led to thread tooth defects. The high-temperature tensile failure modes of the M5 3DN C/SiC bolts mainly included bolt shank fracture and thread stripping. At 1000 ℃

when the tensile displacement reached half of the pitch

matrix cracking occurred and propagated with increasing load. The exposed carbon fibers at the crack sites

subjected to the high-temperature oxidative environment at 1000 ℃

rapidly lost their subsequent load-bearing capacity.
