Outline of Final Research Achievements

Carbon nanotube (CNT) grafting method at the growth temperature of relatively low (550-600 degree Celsius), at which tensile strength of carbon fiber was not degraded, was developed by using Ni as the catalyst and ethanol as the carbon source by catalytic chemical vapor deposition (CCVD) method. CNT grafted carbon fiber showed higher fiber/matrix interfacial share strength than as received carbon fiber. Molding method of Carbon Fiber Reinforced Thermoplastics with low void content was developed by using direct resistance heating to CNT grafted carbon fiber for a hot press molding.
