碳/碳复合材料室温力学性能测试

Room Temperature Mechanical Properties Testing For Carbon/Carbon Composite Materials

文中针对作为飞机发动机尾喷管的三维四向碳/碳复合材料,根据特定工艺和实际情况,总结了一套合理的测试标准,并测试了这种材料的拉伸、弯曲、剪切等力学性能,并分析了断裂机理。

According to the special process and the actual situation, a reasonable testing standard is summed up for the three dimensional carbon/ carbon composite materials that is used in engine tail cone of plane. In this article, the process of tensile test, bending test and shearing test are introduced. At last, the fracture mechanism is discussed, too.
