Outline of Final Research Achievements

To create carbon fiber reinforced composite whose matrix is polymer alloy of polypropylene and polyamide (nylon) (PP/PA), the knowledge about the optimization of the design of interface between carbon fiber and PP/PA resin was investigated by taking into account interfacial shear stress and work of adhesion. The optimum interfacial shear stress and work of adhesion of carbon fiber and PP/PA resin are determined by different mechanism corresponding to the polarity of fiber and the structure of polymer alloy. In conclusion, to develop carbon fiber reinforced plastic composed of polymer alloy, it is important to select optimum chemical modification method of fiber surface in accordance with the components and structure of polymer alloy.
