Some Fundamental Properties of the Interface of Glass—Epoxy Composites

Abstract A fundamental study of phenomena occurring at the interface of glass—resin composites is carried out. The role of water at the interface is examined by utilizing E-glass rods drawn from a melt in an anhydrous atmosphere as a base-line material with which to compare E-glass rods subject to aging, treatments with A-1100 silane, water, and roasting. Model glass—epoxide composites were constructed and examined gravimetrically and radiographically for diffusion of water through them. The influence of the variables mentioned above are also examined by modulus of rupture tests and by scintillation counting, following treatment with tritiated water.
