摘要
根据C/C复合材料室温面内剪切强度实验数据,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,探讨该复合材料的室温面内剪切强度分布规律。根据Kolmogorov非参数检验,对假设分布进行检验。结果表明,C/C复合材料室温面内剪切强度可以用二参数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面内剪切强度。
The in-plane shear strength of C/C composite was measured by compression of double-notched specimens at room temperature. The statistical distribution of the strength was studied by a two parameter Weibull distribution function. A graphic method was applied to estimate the parameters in the distribution. Furthermore, the distribution was verified by Kolmogorv test. The result shows the statistical distribution of in-plane shear strength well follows a two parameter Weibull distribution. The inplane shear strength of C/C composites can be predicted using the gained two parameter Weibull distribution accurately.
