Carbon fiber reinforced composite material

A carbon fiber reinforced composite material comprising:

• carbon fiber;
• and
• a thermosetting resin composition, wherein
• 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 graphene oxide and nanocellulose,
• wherein the graphene oxide is modified by a functional group containing an oxygen atom and is used as it is for further enhancing strength of the composite material,
• 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, and
• 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, and 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.
