Glass fiber reinforced plastic and preparation method thereof

The invention belongs to the technical field of plastics, particularly relates to a glass fiber reinforced plastic and a preparation method thereof, and provides the following scheme aiming at the problems of low bending strength and low strength retention rate in the prior art. The glass fiber reinforced plastic is prepared from the following raw materials in parts by weight: 30 to 40 parts of unsaturated polyester resin, 20 to 25 parts of polyimide resin, 10 to 15 parts of modified glass fiber, 3 to 8 parts of modified kaolin, 5 to 10 parts of modified talcum powder, 5 to 10 parts of nano titanium dioxide, 1 to 5 parts of aluminum hydroxide, 1 to 5 parts of sulfur, 1 to 5 parts of antioxidant and 1 to 3 parts of initiator. The bending strength of the glass fiber reinforced plastic is greatly improved, the application range of the glass fiber reinforced plastic is expanded, and the prepared glass fiber reinforced plastic is high in strength retention rate in a high-temperature environment and can still be no
