Abstract

An improved glass fiber reinforced plastic composite material is prepared from, by weight, 9-11 parts of tetra(2,4-di-t-butylphenyl)-4,4'-biphenyldiphosphite, 6-10 parts of ethylene bisstearamide, 3-8 parts of a titanate coupling agent, 13-15 parts of polyethylene glycol terephthalate resin, 6-8 parts of sodium stearate, 30-45 parts of polyphenyl ether, 9-15 parts of glass fibers, 3.5-8 parts of a silicone lubricant, 7-10 parts of hydroxyphenyl acrylate, 2-4 parts of a lubricant, 3.2-7 parts of N-caproylcaprolactam, 1-3 parts of silicone oil, 40-50 parts of epoxy modified phenolic resin, 2-4 parts of cellulose, 1.4-4 parts of a curing accelerator and 3-6 parts of a mold release agent. The glass fiber reinforced plastic composite material has the advantages of good stability, high mechanical strength and hardness, certain toughness and good comprehensive performances.

Description

technical field [0001] The invention relates to an improved fiberglass composite material. Background technique [0002] Due to the different types of resin used, it is called polyester FRP, epoxy FRP, and phenolic FRP. The characteristics of FRP are light and hard, non-conductive, high mechanical strength, less recycling, corrosion resistance, etc. It can replace various machine parts, automobiles, and ship shells made of steel. The diameter of glass fiber is very small, generally less than 10 μm, with fewer and smaller defects, and the fracture strain is less than 30 / 1000. It is a brittle material that is easy to damage, break and be corroded. Compared with fibers, the strength and modulus of the matrix are much lower, but it can withstand large strains. It often has viscoelasticity and elastoplasticity, and is a tough material. However, FRP is hard and fragile, which limits the scope of use and greatly affects the service life of FRP. Now how to ensure that FRP is not ...
