Tensile strength of polymer composites typically used in pressure vessels is considered. This study combines numerical stress analysis for determining the stress distribution around evolving damage and statistical analysis for determining the rate of subsequent growth. The effect of void content as well as the nonuniformity in the fiber spacing are explicitly considered. The non-uniformity in the fiber spacing was found to degrade the strength of the composite material. The presence of voids in addition to nonuniform fiber spacing further decreased the strength. For the models analyzed, maximum strength loss was estimated to be about 14%, for a composite material with a void volume fraction of 8%.
