Abstract

The invention discloses a graphene modified glass fiber reinforced resin composite material and a preparation method thereof. The preparation method comprises the following steps that 1, glass fibers are prepared; 2, the glass fibers are pretreated; 3, graphene quantum dots are weighed and prepared into a dispersion solution of which the concentration ranges from 0.1 mg / ml to 1 mg / ml, the solvent is water or acetone or dimethyl sulfoxide, ultrasonic stirring is conducted on 80 ml-100 ml of graphene quantum dot dispersion solution, the pretreated glass fibers are added into the graphene quantum dot dispersion solution, the speed of ultrasonic stirring is decreased by half, soaking is conducted for 30 min to 60 min, and the glass fibers are cleaned and dried for use; 4, a graphene modified glass fiber reinforcement is prepared and modified with a silane coupling agent; 5, resin base materials are composited, and the graphene modified glass fiber reinforced resin composite material is obtained. The prepared graphene modified glass fiber reinforced resin composite material has a more excellent mechanical property.

Description

technical field [0001] The invention relates to a graphene modified glass fiber reinforced resin composite material and a preparation method thereof. Background technique [0002] Glass fiber (original name in English: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance. Brittle, poor wear resistance. It is generally made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair 1 / 20~1 / 5 of silk, and each bundle of fiber precursors is composed of hundreds or even thousands of single filaments. [0003] Graphene, as an allotrope of carbon, is a single-layer two-dimensional crystal material with a honeycomb structure formed by the hybridization of carbon atoms according to sp2 orbitals. Graphene has good mechanical properties and chemical stability, which will also be us...
