The invention discloses high-strength temperature-resistance glass fiber reinforced plastic. The high-strength temperature-resistance glass fiber reinforced plastic is prepared from, by mass, 30-40 parts of unsaturated polyester resin, 10-30 parts of hydrogen peroxide, 1-3 parts of potassium oxide, 1-3 parts of phenol modified tungsten hexachloride, 2-4 parts of titanium dioxide, 1-3 parts of magnesium oxide, 5-7 parts of calcium oxide, 6-8 parts of calcium sillicate, 1-5 parts of fire retardant, 2-4 parts of nano silicon dioxide, 10-20 parts of glass fiber, 1-3 parts of tungsten powder, 2-8 parts of ultraviolet absorbent, 10-12 parts of nano carbon fiber and 5-10 parts of silicon carbide powder. The high-strength temperature-resistance glass fiber reinforced plastic is simple in process,environmental-friendly and free from pollution, the prepared glass fiber reinforced plastic has the advantages of high strength, high-temperature resistance, ultraviolet resistance and the like, and the service life is greatly prolonged.
