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-0 0 , UD-90 0 , fabric-0 0 , fabric-90 0 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 0 0 with a non-tabbing treatment. This was due to the inhomogeneous of the data.
