Description

technical field [0001] The invention relates to the technical field of FRP grids, in particular to a high-strength FRP grid material. Background technique [0002] Molded glass fiber reinforced plastic grating (referred to as FRP grating) is a kind of glass fiber reinforced material, unsaturated polyester resin as matrix, which is made by manual winding and resin casting method with many regular spaces. of sheet material. Because of its excellent corrosion resistance, flame retardant, light weight and high strength, impact resistance, insulation, non-slip, non-magnetic, beautiful, maintenance-free, easy installation, aging resistance, fatigue resistance and other characteristics, it is widely used in petrochemical, metallurgy, electric power , food, transportation, environmental protection and many other industrial fields. Under the action of external factors for a long time, the general FRP grating will break or catch fire under the influence of high temperature. Conten...
