| Description | It is well known that the mechanical properties of glass fiber reinforced composites are influenced by the adhesive property of glass fiber / resin matrix interface. The adhesive property is very influenced by silane coupling agent that is widely used as an adhesive agent between glass fiber and resin. The contribution of silane coupling agent on glass fiber / matrix interface is based on the chemical bonding of silane to both resin and glass surface. In order to investigate the reaction of silane-treated glass fiber to thermosetting resin, a lot of spectra were measured near interface between the glass fiber and vinyl ester resin using microscopic FT-IR spectroscopy. A thin sliced sample was made from glass fiber / vinyl ester resin composite to be subjected to the FT-IR measurement. The spectra were obtained through a 20 μm X 40 μm of a mask window at each 20 μm step from the glass strand area to the matrix resin. The intensity at 1450 $cm^{−1}$ due to vinyl ester resin was found to increase from the matrix resin to the glass strand area. This meant that silane coupling agent affected the harslening system of the resin near fiber in glass strand area. It was, however, noticed that the intensity kept the same value even in matrix of 80 μm far from glass strand area. This suggested that the resin in such an area was denatured by the reaction of silane to resin at the surface. This mechanism was supported by an significant size of the denatured area which increased with amounts of silane at the surface of glass fiber. In addition, the change of denatured area was found to depend on the amounts, but on the binding state of silane to glass fiber such as chemical bond and physisorption.
