Statistical analysis of CFRP mechanical properties using B-basis based on weibull and ANOVA distribution analysis

Abstract

In this paper, the mechanical properties of composite materials are subjected to statistical analysis. This study aimed to determine the value of B-Basis strength parameters of carbon composite material with UD-00, UD-900, fabric-00, fabric-900 from the results of tensile and compression tests. The maximum normal residual test was used for outlier identification and k-sample Anderson's darling test to determine whether parameters can be processed as one large group of data. The scope of this study focused on evaluating B-Basis values using two methods: Weibull and ANOVA. The results showed that Weibull distribution method could be applied to analysis the data and produced a confidence level of 95%. ANOVA method however, could not be applied to specific data which were the tensile strength of UD 00 with a non-tabbing treatment. This was due to the inhomogeneous of the data.
