CARBON FIBER CHOPPED STRAND FOR THERMOPLASTIC RESIN AND FIBER REINFORCED COMPOSITE MATERIAL

摘要

PPROBLEM TO BE SOLVED: To provide a carbon fiber chopped strand for thermoplastic resin having high adhesiveness to a matrix resin and excellent in a bundling property and forming stability and a fiber-reinforced composite material using the chopped strand. PSOLUTION: In the carbon fiber chopped strand for thermoplastic resins, total content of a monovalent or divalent metal element measured by a flame atomic absorption method is 50-600 ppm and the amount of a sizing agent added to the strand is 1.5-6.0 mass%. The fiber-reinforced composite material comprises the chopped strand and a thermoplastic resin. PCOPYRIGHT: (C)2004,JPO&NCIPI
