Abstract

The interfacial adhesion and the mechanical properties of glass fiber reinforced epoxy matrix composite were studied systematically by changing the ratio of the curing agent to epoxy and also the surface treatment of fibers. A strong correlation between the interfacial shear strength and the work of adhesion was found, i.e., the interfacial shear strength is scaled linearly with the interfacial work of adhesion. An empirical formula has been proposed for the relation between the interfacial shear strength and the work of adhesion, from which the equilibrium interatomic distance at the interface between matrix and fiber was evaluated.
