CARBON FIBER-REINFORCED COMPOSITE MATERIAL, PREPREG, AND METHOD OF MANUFACTURING CARBON FIBER-REINFORCED COMPOSITE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a prepreg that can form an carbon fiber-reinforced composite material excellent in interlayer toughness and the conductivity of a Z-axis direction.;SOLUTION: The carbon fiber-reinforced composite material includes: a resin layer including: a resin particle containing a matrix resin and a polyamide resin having a structure shown by formula (1); and a conductive particle whose average particle diameter is larger than that of the resin particle; and carbon fiber layers provided on both principal planes of the resin layer and containing a carbon fiber, wherein the difference between the average thickness of the resin layer and the average particle diameter of the resin particle including the polyamide resin having the structure shown by the following formula (1) is at most 12 μm. In the formula, a and b denote an integer of 0-4, R¹ and R² each independently denote an alkyl group or a halogen atom, and R³ denotes an alkanediyl group, a cycloalkanediyl group or an alkenediyl group.;COPYRIGHT: (C)2013,JPO&INPIT
