High temperature-resistant glass fiber reinforced plastic composite material

Abstract

The invention discloses a high temperature-resistant glass fiber reinforced plastic composite material. The composite material is prepared through mixing 25-29 parts of phenolic resin, 20-25 parts of bisphenol A epoxy vinyl resin, 60-70 parts of glass fibers, 7-9 parts of dibutyl phthalate, 6-7 parts of ethylene diamine, 1-4 parts of ethylene ethanol and 10-12 parts of calcium carbonate. The composite material has the advantages of strong high temperature resistance, effective prevention of the abuse of strength decrease due to too high temperature, good anticorrosive performance, strong ageing resistance and good shearing resistance.

Description

technical field [0001] The invention relates to a glass fiber reinforced plastic material, in particular to a high temperature resistant glass fiber reinforced plastic composite material. Background technique [0002] The concept of composite material refers to a material that cannot meet the requirements of use, and needs to be combined by two or more materials to form another material that can meet people's requirements, that is, a composite material. For example, although a single glass fiber has high strength, the fibers are loose and can only bear tensile force, but cannot bear bending, shearing and compressive stress, and it is not easy to make a fixed geometric shape, so it is a soft body. If they are bonded together with synthetic resins, they can be made into various hard products with fixed shape, which not only can bear tensile stress, but also can endure bending, compression and shearing stress. Because its strength is equivalent to steel, and it contains glass ...
