Abstract

The flexural strength of a 3D Hi-Nicalon/SiC composite was tested using the three point bending method at room temperature and the strength distribution was studied based on Weibull distribution. A graphical method and the stepwise regression were applied to optimizing the estimated parameters. Furthermore, the validity of the assumed distribution was examined by the Kolmogorov test. The results indicate that the statistical distribution of 3D Hi-Nicalon/SiC is in agreement with a two-parameter Weibull distribution characterized by σ_u=0 and the Weibull modulus, m=8.1545. The strength distribution of the 3D Hi-Nicalon/SiC composite in the three point bending test can be accurately predicted using the gained two-parameter Weibull distribution.
