Technical Field

The invention relates to a glass fiber reinforced plastic material, in particular to a flame-retardant high-temperature-resistant glass fiber reinforced plastic composite material.

Background

Glass Fiber Reinforced Plastics (FRP), also known as GFRP, is a fiber reinforced plastic, generally a reinforced plastic made of a matrix of unsaturated polyester, epoxy resin and phenolic resin reinforced with glass fibers or products thereof, and is called glass fiber reinforced plastic, or glass fiber reinforced plastic, different from tempered glass.

The glass fiber reinforced plastic has the advantages of light weight, hardness, non-conductivity, stable performance, high mechanical strength, less recycling and corrosion resistance, and is widely applied to the fields of replacing steel products to manufacture machine parts, automobile shells, ship shells and the like.

The traditional epoxy glass fiber reinforced plastic is not high temperature resistant and can not be applied to the fields of chemical industry and metallurgy; in addition, since glass fiber reinforced plastics are mostly used in public places and conventional glass fiber reinforced plastics composite materials have no flame retardancy, when a fire breaks out, the glass fiber reinforced plastics may aggravate the spread of the fire and generate a large amount of black smoke.
