EFFECT OF MORPHOLGY ON MECHANICAL PROPERTIES OF COMPOSITES PREPARED BY REACTION-INDUCED PHASE SEPARATION

摘要

A new class of fiber-reinforced composite materials was designed in our laboratory by using a hybrid of thermoplastic and thermosetting polymers. The thermosetting polymer phase separates upon curing reaction and creates morphology on the fiber surfaces. Effect of the morphology is studied on the fracture toughness of the composite, with the aim of enhancing the mechanical properties of the resulting fiber reinforced composite.
