Novel glass fiber-reinforced plastic material

Abstract

The invention discloses a novel glass fiber-reinforced plastic material. The novel glass fiber-reinforced plastic material comprises, by mass, 25-30 parts of epoxy resin, 15-25 parts of polyester resin, 42-55 parts of glass fiber, 3-5 parts of emulsified paraffin, 1-2 parts of polyamide, 6-8 parts of dibutyl phthalate, 4-6 parts of silicon carbide micropowder and 3-4 parts of a coupling agent. Thenovel glass fiber-reinforced plastic material of the invention is high in elastic modulus, good in rigidity, not prone to deformation and high in thermal endurance, prevents long period of high temperature from affecting strength, and has strong anti-aging ability and good shearing resistance.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a novel glass fiber reinforced plastic material. Background technique [0002] Glass is hard but brittle, and has good transparency, high temperature resistance, and corrosion resistance. At the same time, steel is hard and not brittle, and it also has the characteristics of high temperature resistance. So people began to think that if they could make a material that not only has the hardness, high temperature resistance, and corrosion resistance of glass, but also has the characteristics of being hard and unbreakable like steel, then this material will definitely be of great use. After research and experimentation, people have finally produced such a composite material, which is FRP that can stand shoulder to shoulder with steel. However, FRP generally has problems such as low elastic modulus, poor long-term temperature resistance, prominent aging phenom...
