Abstract

The kinetics of thermal degradation and its consequent effects on the mechanism of microcracking in carbon fibre composites fabricated from PMR-15, an end-capped bismaleimide resin system, have been studied under oxidative conditions. The overall degradation involves three stages. For the unidirectional laminates, oxidative decomposition of resin appears to control the micromechanics of their durability, whereas changes in thermomechanical properties of the matrix seems to be responsible for the formation of transverse cracks in the cross-ply laminates.
