Abstract

The invention relates to a carbon fiber composite material with interlayer shear performance and a preparation method thereof. The composite material includes carbon fibers, an epoxy resin matrix material and micro-nano materials dispersed in the epoxy resin matrix material in an orientation; the micro-nano materials are Refers to graphene oxide surface modified with magnetic nanoparticles. The invention uses graphene oxide modified by magnetic field orientation magnetic particles to enhance the interlayer shear performance of the carbon fiber composite material, while strengthening the matrix resin, the interface between the matrix resin and the carbon fiber is combined more firmly, so that the prepared composite material has Excellent interlaminar shear properties.

Description

technical field [0001] The invention belongs to the field of preparation of polymer-based composite materials, and in particular relates to a high-layer inter-shear performance carbon fiber composite material and a preparation method thereof. Background technique [0002] Carbon fiber / epoxy composite materials have the unique advantages of high specific strength and specific stiffness, strong designability, good fatigue fracture resistance, corrosion resistance, good structural dimensional stability, and easy large-area overall molding, and are widely used in aerospace. , sports equipment, automobiles and other fields of the national economy. However, a considerable number of products in carbon fiber composite materials are laminated plate structures. Since the carbon fiber layers are completely dependent on the bonding of resin, the interlayer shear performance of carbon fiber composite materials is relatively poor, resulting in the material being in use. Cracking occurs b...
