Issues in Matrix Composites

In matrix composites, the failure is often due to creep rupture. For matrix composites, suitable models should incorporate features such as environmentally driven, statistical degradation mechanisms both in the glass fiber, and in the polymer matrix. Relevant knowledge concerning this special topic has been compiled in the literature (9). 

The model should produce statistical statements on the lifetime in terms of the overall applied stress field, the overall volume of material, and boundary effects. Important input parameters are fiber packing geometry, fiber strength, matrix and interface creep exponents, rate factors in the stress-corrosion chemistry, and the applied stress level.
