Abstract: The properties of the interphase formed between glass fibre with differing silane coupling agents and a vinylester resin are characterised using novel experimental techniques, including nanoindentation and nanoscratch tests and thermal capacity jump measurement. The effective interphase thickness measured from the nanoscratch test varies between 0.8μm and 1.6μm depending on the type and concentration of silane agent. These values are consistent with those measured based on the heat capacity changes, in terms of both general trend and absolute quantity. They increase with increasing silane concentration, as expected. The nanoindentation test is not sensitive enough to distinguish the difference in interphase thickness due to different silane agents, while it gave the interphase thickness approximately 1μm, with some varying elastic modulus and hardness values for the matrix resin.
