Carbon fiber reinforced resin composite material as well as preparation method and application thereof

The invention discloses a carbon fiber reinforced resin composite material as well as a preparation method and application thereof, which are used for solving the problem of poor heat-conducting and flame-retardant properties of a carbon fiber resin-based composite material. The carbon fiber reinforced resin composite material is prepared from the following raw materials in parts by weight: 32 to 42 parts of prefabricated resin, 0.5 to 16.5 parts of curing agent and 37.5 to 67.5 parts of carbon fiber, the prefabricated resin is prepared from the following raw materials in parts by weight: 2 to 8 parts of modified magnetic boron nitride, 0.5 to 2.0 parts of modified graphene and 29.5 to 35 parts of resin; in the composite material, the modified magnetic boron nitride is vertically oriented, and the modified graphene is transversely connected with the oriented modified magnetic boron nitride. The modified magnetic boron nitride is connected with the carbon fibers in a vertical orientation mode, the modified gra
