Room temperature compression strength distribution of medium density puncture C/C composites

本文根据C/C复合材料室温压缩强度实验数据,以二参数Weibull分布为假设分布模型,采用图解法进行参数估计,探讨该复合材料室温压缩强度分布规律,根据Kolmogorov分参数检验,对假设分布进行检验。结果表明,C/C复合材料室温压缩强度可以用二参数Weibull分布模型表征,求解的二参数Weibull分布能很好地预测该材料的室温压缩强度。

In this paper,based on the experimental data of C/C composite compressive strength at room temperature,the twoparameter Weibull distribution was used as the hypothesis distribution model,and the parameter estimation was carried out by graphical method to explore the distribution law of the compressive strength at room temperature of the composite.The hypothesis distribution was tested according to Kolmogorov parameter test.The results show that the room temperature compressive strength of C/C composites can be characterized by the two-parameter Weibull distribution model,and the two-parameter Weibull distribution can predict the room temperature compressive strength of this material well.
