碳-碳复合材料高温力学性能测试温度高,材料应变量小。采用通电加热、非接触应变测置较能适应其测试特点。本文介绍了采用这种方法进行拉伸试验的情况,并提供了2000℃范围内的拉伸应力-应变曲线,给出了抗拉强度、断裂应变数据以及弹性模量的参考值。 Carbon-carbon composite materials, high temperature mechanical properties of the test temperature is high, the material strain is small. The use of electricity heating, non-contact strain gauge more able to adapt to its testing features. This paper presents the case of tensile testing using this method and provides a tensile stress-strain curve in the 2000 ° C range with reference values ​​for tensile strength, strain at break and modulus of elasticity.
