The major objectives of this research was to develop a high performance polymer matrix composites by morphology control using nano-fillers. The summaries of this research are as follows ;(1) PVC was an effective material for controlling the morphology in nano-scale.(2) Uniformity of reaction on the fiber/matrix interface was important for the interfacial strength, and the molecular weight of the matrix resin should be in the range which the molecular chains near the interface could be tangled with the molecular chains in the bulk polymer.(3) The interfacial strength in multi phase polymers was correlated to the toughening mechanisms.(4) The toughening of the interlaminar resin region was useful technique for the development of the glass cloth reinforced polymer composites with high strength and toughness.(5) It was possible to control the interfacial structure of silane coupling agent in the glass fiber reinforced polymer composites by annealing.
