摘　　要：基于2D-C/SiC复合材料面内剪切强度实验数据,以双参数Weibull分布为假设分布模型,采用线性回归法进行参数估计,结合Kolmogorov非参数检验,针对2D-C/SiC复合材料面内剪切强度分布规律进行研究。结果表明:2D-C/SiC复合材料面内剪切强度服从双参数Weibull分布,利用双参数Weibull分布预测2D-C/SiC复合材料面内剪切强度与实验值吻合较好。Based on the tests data of 2D-C/SiC composite,the statistical distribution of the in-plane shear strength is studied by a double parameters Weibull distribution function.The distribution and parameters about in-plane shear strength of 2D-C/SiC composites are determined by liner regression combined method and hypothesis testing.The results show that the in-plane shear strength of 2D-C/SiC composites follows double parameters Weibull distribution,and the prediction strength has good agreement with test data.
