The present invention discloses a fiberglass pultrusion pressing strip for fixing a generator rotor magnet steel. The fiberglass pultrusion pressing strip is formed by a matrix material and a reinforcing material. The matrix material comprises, by weight, 100 parts of epoxy resins, 70 to 85 parts of anhydrides, 2 to 3 parts of epoxy accelerants, 2 to 3 parts of epoxy accelerant releasing agents, 20 parts of flame retardants and 2 to 3 parts of color pastes. The reinforcing material comprises continuous mats with the volume of 1 to 2 to 10, multiaxial fabric and an alkali-free glass fiber. The fiberglass pull extrusion strip has the advantages that the fiberglass pultrusion pressing strip is formed by fiberglass pultrusion process, the production efficiency is high, the size of the pressing strip is accurate, the temperature resistance and mechanical performance of the pressing stripe are improved, the flame retardant performance passes a glow-wire (960+/-15 DEG C) 30s test, the anti-split strength is larger than 5000N/cm, the notch bearing capacity of the pressing strip is larger than 7000N, and the scope of application of the device is raised.
