Abstract

The invention relates to the technical field of glass fiber composite materials, in particular to a glass fiber resin composite material and a preparation method thereof. The raw materials of the glass fiber resin composite material comprise glass fiber cloth and an epoxy resin base material glue solution, wherein the weight ratio of the glass fiber cloth to the epoxy resin base material glue solution is 7: (3-3.5), and the epoxy resin base material glue solution is prepared from the following raw materials in parts by weight: 80-110 parts of epoxy resin, 8-10 parts of porous glass micro-beads, 12-16 parts of alumina powder, 5-9 parts of a dispersing agent and 2-5 parts of an adhesive. According to the invention, porous glass micro-beads are treated to form high-strength and high-dispersity microspheres, the high-strength and high-dispersity microspheres are uniformly mixed with epoxy resin to prepare an epoxy resin base material glue solution, glass fiber cloth quickly passes through the molten epoxy resin base material glue solution, the surface of the glass fiber cloth is quickly coated with the epoxy resin base material glue solution, and the hardness and the strength of the formed glass fiber resin composite material are greatly improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber composite materials, in particular to a glass fiber resin composite material and a preparation method thereof. Background technique [0002] Commonly used glass fiber composite materials refer to resin-based composite materials, which can be formed by hand lay-up, winding, pressing and other molding processes, as well as injection and pultrusion molding processes. Due to the characteristics of light weight, corrosion resistance and insulation, glass fiber reinforced composite materials can be widely used in hand machinery, chemical industry, transportation and other fields. In the military field, it can be used for radomes, fairings, missile warheads and solid rocket launchers to sweep L ablation heat-resistant layers, missile launchers, firearms and mountain combat vehicle structural parts, etc. [0003] The existing glass fiber resin composite materials still need to be improved in properti...
