Tension-Softening Relation for Short-Fiber-Reinforced Composites and Examination of the Experimental Results at Law Temperature

Abstract

A Probabilistic model is used to derive the tension-softening relation for short-fiber-reinforced composites. By the use of the tension-softening relation, the fracture energy and the load-displacement relation can be obtained. We applied it to a short-fiber-reinforced SMC composite at low temperature. From the results, we realized quantitatively that the fracture energy increased and the SMC composite was strengthened at low temperature.
