Abstract

The invention relates to a carbon fiber composite material and a preparation method thereof, and belongs to the technical field of carbon fiber composite materials. The carbon fiber composite materialincludes 0.5-1 m<2> of carbon fibers, and also includes, by weight, 20-30 parts of E-51 epoxy resin, 20-30 parts of E-42 epoxy resin, 20-30 parts of TDE-86 epoxy resin, 10-20 parts of methylenebiscyclohexylamine, 15-25 parts of an ED-600 curing agent, 10-20 parts of trimethylolpropane triglycidyl ether, 5-10 parts of triethylene diamine and 30-50 parts of acetone. Good curing of a carbon fiber-epoxy resin curing system is realized in a low temperature range from the epoxy resin curing agent and the curing process, so the carbon fiber composite material which can be cured at a medium temperature, achieves wet production of a prepreg and has excellent mechanical properties is prepared.
