Abstract

The invention relates to the technical field of composite materials and particularly relates to a preparation method of an improved epoxy resin-based glass fiber composite material. The composition comprises the following raw materials in parts by weight: 100-120 parts of epoxy resin, 20 to 25 parts of silicon dioxide nanometer particles; 5-10 parts of a curing agent and 1-3 parts of an adhesive.According to the preparation method, nano particles are uniformly dispersed in a monomer by adopting ultrasonic waves; polymerization reaction is then carried out, so that the heat resistance, the strength, the hardness, the wear resistance and the corrosion resistance of the resin-based glass fiber composite material can be greatly improved; finally, silicon dioxide nanoparticles are combined toprepare a complex with pores below 100 nm, and then the complex is compounded with glass fibers (the diameter is 11mu m and the length is 3mm); therefore, the prepared composite material has excellentheat resistance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an improved method for preparing epoxy resin-based glass fiber composite materials. Background technique [0002] The manufacturing process of traditional high-temperature glass fiber composite materials is to change the resin molding system of glass fiber material and use high-temperature resistant polyimide resin to make it. Because of its high price and complex production process, the domestic price of high-temperature-resistant composite glass fiber materials has been at a high level. However, using silica nano-reinforcement technology, a composite glass fiber material with a similar temperature resistance level can be produced by using a low-cost epoxy resin gluing system. Epoxy resin-based glass fiber composites have excellent mechanical properties, corrosion resistance and chemical stability; small volume shrinkage during processing; low cost and other outstan...
