Abstract

This paper describes modeling of degradation mechanisms for high-temperature polymer matrix composites under thermo-oxidative aging conditions. Thermooxidative aging is simulated with a diffusion/reaction model in which temperature, oxygen concentration and weight loss effects are considered. One-dimensional and three-dimensional simulations illustrate oxidative layer growth for neat resin and composite unit-cell geometries. The effect of a highly diffusive fiber-matrix interface on the homogenized behavior of the composite is studied. The effect of damage on the lamina-scale diffusivity of the composite is also simulated using unit-cell modeling. Copyright
