Abstract

In fiber-reinforced toughened polymers, the influence of matrix deformation needs to be properly considered in their failure processes. There is a transition from failure dominated by massive matrix plasticity to that dominated by fiber-related mechanisms as the fiber content increases. This paper addresses some experimental observations and physical rationalization of the complex events that lead to failure of short fiber reinforced toughened nylon 6,6. The toughening behavior was studied using fracture mechanics techniques. The essential work of fracture analysis shows that the inclusions of short glass fibers not only provided a stiffening effect but also a toughening influence.
