There are many kinds of FRP pultrusion profiles, glass fiber reinforced plastic round tube, glass fiber reinforced plastic square tube, glass fiber reinforced plastic rectangular tube, glass fiber reinforced plastic bar, glass fiber reinforced plastic I-beam.
The basic components of pultruded FRP profiles are resin and glass fiber (including cloth, felt, etc.), which is reinforced by fiber (including glass fiber, carbon fiber, fiber and other metal, non-metal fiber) and resin (mainly epoxy resin). Polyester resin, phenolic resin) is a binding agent, supplemented by other auxiliary materials (main auxiliary materials: release agent, curing agent, catalyst, sealing agent, UV light stabilizer, cleaning water, gelcoat, etc.) composite. It has a series of excellent characteristics such as high temperature resistance, resistance, high strength, small specific gravity, low moisture absorption, small extension and good insulation.
