New procedure to couple glass beads with epoxy resin has been proposed. Bisphenol A type of epoxy resin (E828) cured with ethylenediamine (EDA) is reinforced by glass beads (GB's). GB's surface treated by silane coupling agents (SA) are mixed with E828 at 100°C~180°C before the curing agent EDA is added, in order to increase the reaction between the SA and E828. As a result, the glass transition temperature, flexural modulus and strength of composites mixed at 150°C have exhibited the highest values, respectively. Moreover, the scanning electron microscopy observation of the fractured surfaces of composites has shown that the method of mixing at 150°C is effective to improve the GB / E828 interfacial adhesion.
