Outline of Final Research Achievements

An aligned CNT composites based on thermosetting polyimide TriA-X, thermoplastic polyimide ISAS-TPI, and these blends were prepared and evaluated. In the resin film infusion method, it was impossible to sufficiently impregnate because of its high melt viscosity. In the polyimide solution prepreg route, an aligned CNT / polyimide composites having a thickness of 0.02 to 0.1 mm could be prepared. The aligned CNT / polyimide composites showed significant improvements in tensile strength and modulus compared with resin.
