COLORED CARBON FIBER

摘要

PROBLEM TO BE SOLVED: To provide a colored carbon fiber for producing a carbon fiber-reinforced composite material having high design flexibility to satisfy simultaneously expression of texture pattern or the like and color development. SOLUTION: The colored carbon fiber has a lightness (L*) not less than 20 in an L*a*b* colorimetric system measured by reflection spectrum of visible range at an incidence angle of 60°and a light receiving angle of 45°. Above all, the fiber preferably has a chroma (ΔC*ab) not less than 2 in the L*a*b* colorimetric system. More preferably, the fiber has a color difference (ΔE*ab) not less than20 in the L*a*b* colorimetric system. COPYRIGHT: (C)2011,JPO&INPIT
