Zusammenfassung:A carbon fiber reinforced composite material includes carbon fiber and a thermosetting resin composition. The thermosetting resin composition is a cured product of a liquid composition that contains unsaturated polyester, a curing agent, a polymerization initiator, and a nanocarbon/nanocellulose complex containing nanocarbon modified by functional a group and nanocellulose. The nanocarbon/nanocellulose complex is dispersed in the thermosetting resin composition. The thermosetting resin composition contains 0.05 to 15% by weight of the nanocarbon/nanocellulose complex. A maximum point stress of the carbon fiber reinforced composite material in a tensile test according to JIS K 7164 is 410 N/mm2 or more. A maximum point stress of the carbon fiber reinforced composite material in a three-point bending test according to JIS K 7171 is 310 N/mm2 or more. The carbon fiber reinforced composite material having excellent mechanical properties can be provided at low cost.
