摘要：

In the present work, two parameter Weibull distribution is used to measure the variability of the tensile strength of cross ply glass/epoxy, carbon/epoxy and hybrid (glass-carbon/epoxy) composites for different strain rates from 0.0083 to 542 s(-1). The Weibull parameters (shape and scale parameters) are obtained using linear curve fit method. The shape and scale parameters will be useful for composite product designers to quantify the component reliability. Using Hitachi SEM instrument, the failure mechanisms observed in the tested samples of GFRP, CFRP and hybrid composites, are discussed.
