Epoxy resins are widely used as the matrix material for fiber reinforced composites in aircrafts, automobiles, ships and housing. Most of the reinforcement in epoxy composite is glass fiber so as to lower the cost. Studies in the past have suggested that composite performance can be improved by modifying the fiber-matrix interface. One approach to modifying the interface is to use silane coupling agents that promote substrate-matrix interfacial adhesion. In this paper we discuss the impact of covalent bonding on fiber-matrix interfacial shear strength, fiber-matrix debonding, and matrix crack formation.
