▎ 摘　　要

NOVELTY - Preparing graphene oxide reinforced carbide hardening composite material comprises mixing carbonized gel material with graphene oxide and water uniformly to obtain the target mixture, pouring the target mixture into the mold, forming and carbonizing to obtain the graphene oxide reinforced carbide hardening composite material, where the mass ratio of the carbonized gel material and the graphene oxide to the water is 1: (0.06-0.30). USE - The method is useful for preparing graphene oxide reinforced carbide hardening composite material. ADVANTAGE - The method has simple operation, low graphite oxide doping amount; is economical; ensures that the growth direction of the calcium carbonate tends to be disorder, thus inhibits the expansion of the internal micro-crack and reduces the porosity; and improves the intensity of the carbonization hardening composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene oxide reinforced carbide hardening composite material, is obtained by the method.
