| 摘 要： | 文摘采用试验的方法研究了两种不同结构C/C复合材料螺栓的拉伸破坏形式。结果表明,螺栓头的结构决定了其破坏模式。对于受拉而导致的螺栓头剪切破坏,不是由单方向的层间剪切和面内剪切决定,而是两个方向剪切综合作用的结果,因此细化螺栓头结构设计能最大程度发挥复合材料的力学性能极限。

| Abstract: | Experimental method was used to investigate the tensile failure modes of two different C/C composites bolts in this paper.Test results indicated that the failure modes were determined by the type of the structure of the bolt head. For the shear failure of the bolt head caused by the tensile load,the comprehensive effect of both the interlaminar and intralaminar shear load is the main factor, but not a single shear load.As a result,improve the design of the structure of the bolt head can enhance the strength of the composites. |
