The invention discloses a preparation method of a carbon nano-tube/amorphous carbon/epoxy resin composite material, belonging to the field of synthesis and application of carbon nano composite materials. The method comprises the steps of firstly, preparing carbon nano-tube sponge; secondly, preparing a carbon nano-tube/amorphous carbon composite material; finally, preparing the carbon nano-tube/amorphous carbon/epoxy resin composite material. A carbon nano-tube/amorphous carbon aerogel is prepared by using a chemical vapor deposition method, and epoxy resin is directly poured into pores of the carbon nano-tube/amorphous carbon aerogel by using the porosity of the carbon nano-tube/amorphous carbon aerogel, thus achieving the effect of enhancing the epoxy resin and directly obtaining the carbon nano-tube/amorphous carbon/epoxy resin composite material with a uniform structure at the same time. The strength and modulus of the prepared carbon nano-tube/amorphous carbon/epoxy resin composite material disclosed by the invention are improved greatly as compared with those of pure epoxy resin and carbon nano-tube/epoxy resin.

The invention discloses a preparation method of a graphene aerogel epoxy resin composite fracturing proppant. The preparation method comprises the following steps: 1, dropping a certain concentrationof graphene oxide suspension in a frozen mixture of petroleum ether and methyl silicone oil to form graphene oxide droplets; 2, moving the graphene oxide droplets in a freeze dryer for freeze drying to obtain graphene oxide aerogel pellets; 3, performing high-temperature thermal reduction on the graphene oxide aerogel pellets into graphene aerogel pellets; 4, introducing the graphene aerogel pellets into an epoxy resin and curing agent mixture for vacuum compounding and then heating and curing to form the grapheme epoxy resin composite fracturing proppant; the pellet type fracturing proppant made by graphene aerogel and epoxy resin compounding has the advantages of low density and high compression strength and can significantly improve the fracturing and yield-increasing efficiencies.
