The FRP profiles produced are smooth and smooth, with good gloss, high strength and toughness. If the use of inferior resin will be completely opposite inferior resin turbidities, high viscosity, high heat release, high shrinkage, relatively slow curing, compatibility is poor, the production of FRP profiles with pores, easy to fracture, poor strength and toughness. The second is the comparison of finished products. Good FRP profile products have no obvious cracks, fewer pores, bright and pure color, good transparency, a certain toughness and strength, good surface finish, long service life; The appearance of inferior FRP products has cracks, more pores, color impure gloss is not enough. Its service life is also short.
