PROBLEM TO BE SOLVED: To provide a structural material excellent in moldability and mechanical property, with high flexural strength and high fluidity by improving resin impregnation performance to a fiber bundle, in a composite material composed of long carbon fiber and polyamide resin composition with a crystallization rate from a molten state in a specified range.SOLUTION: There are provided long carbon fiber reinforced polyamide resin prepreg and/or molding, each of which contains a carbon fiber of 40 to 80 mass%, and has, as a base material, a polyamide resin in which a difference between a melting peak temperature Tm and a crystallization peak temperature Tc is 20 to 60°C. |
