Abstract

Oxidation growth and damage evolution are highly coupled in polymer composites operating at elevated temperatures. A comprehensive Oxidation-Mechanics-Damage model that considers the coupling between oxidation growth and damage evolution is presented in this paper. Using oxidation-induced stress, detailed damage evolution and crack surfaces are obtained. The effect of damage evolution on oxidation progression is also predicted. Simulations are conducted for G30/PMR-15 high-temperature polymer composites along the fiber direction and the predicted oxidation growth and damage evolution correlated well with experimental results.
