An investigation was performed on the interface control of FRP using glass fiber treated by low temperature plasma.The teratment apparatus was developed in order to control plasma coating onto plain woven glass cloth.Three-point flexural tests of glass fiber reinforced epoxy composites were done by an Instron testing machine in order to examine the effect of the plasma teratment on the composite properties.The main results obtained were as follows:(1) NH_3 gas plasma teratment was applied to improve the surface properties of the fiber.The contact angle between destilled water and surface of glass slide,substituted for the glass fiber to measure the contact angle,was decreased by this treatment.And the bending strength of FRP prepared with NH_3 plasma treated fiber became higher than the one with the untreated fiber.(2) The bending strength of FRP varied as a function of plasma parameters such as the treatment power and the treatment pressure.(3) The improved adhesion state of the epoxy resin onto the glass fiber after NH_3 gas plasma treatment was revealed by the SEM observation of the tensile fracture surface.It can be concluded from these results that the interfacial adhesion and the mechanical interlocking were increased by this process.
