针对同批炭/炭复合材料力学性能测试结果相差较大的情况,从取样、试样加工过程和工艺试验研究入手,通过分析其力学性能测试结果,对加工参数、加工方法对炭/炭复合材料力学性能测试的影响程度进行了研究,结合对所加工试样的表观质量分析,系统地探讨各种参数的影响,给出适合炭/炭复合材料试样加工的最优切削参数,并给出试样界面尺寸的公差控制范围,有效地降低了炭/炭复合材料试样力学性能测试的偏差。 Aiming at the big difference between the test results of the mechanical properties of the same batch carbon / carbon composites, this paper starts with the sampling, the sample processing and the process experiment. By analyzing the mechanical performance test results, the processing parameters, processing methods, The influence of various parameters was discussed systematically based on the apparent quality analysis of the processed samples. The optimal cutting parameters suitable for the processing of carbon / carbon composite samples were given. The control range of the interface size of the sample is given, which effectively reduces the deviation of the mechanical properties of the carbon / carbon composite sample.
