本文叙述了用悬挂共振的原理测试碳素材料高温弹性模量的动态测试方法,试样采用钨链悬挂、石墨炉加热并充氩气保护,最高测试温度为2600℃。文中对测试结果进行了误差分析,并将金属钨、石墨和三向编织碳-碳材料z、xy、45°三个取向试样的动态法测试数据与文献数据进行了比较,三向碳-碳材料的测试结果也与静态法测试数据进行了对比,结果较为一致。 In this paper, the dynamic test method for measuring the high temperature elastic modulus of carbon materials by the principle of suspension resonance is described. The sample is heated by a tungsten chain, heated by a graphite furnace and protected by argon gas. The maximum test temperature is 2600 ℃. The error analysis of the test results was carried out in this paper. The dynamic test data of three orientated samples of tungsten, graphite and three-directional braided carbon-carbon materials at z, xy and 45 ° were compared with the literature data. The three- Carbon material test results are also compared with the static test data, the results are more consistent.
