A Fiberglass reinforced plastic is on the basis of original pure plastic, adding glass fiber and other additives, so as to improve the scope of use of materials.Generally speaking, most of the glass fiber reinforced materials are used in the structural parts of the product, which is a kind of structural engineering materials
Advantages:
1 After fiberglass reinforcement, fiber glass is a high-temperature resistant material. Therefore, the heat resistance temperature of reinforced plastics is much higher than that before without glass fiber, especially nylon plastics;
2 After fiber glass reinforcement, because of the addition of fiber glass, the mutual movement between the polymer chains of plastic is limited, so the shrinkage rate of reinforced plastic decreases a lot, and the rigidity is greatly improved;
3 Fiber glass reinforced, reinforced plastic will not stress cracking, at the same time, the impact resistance of plastic improved a lot;
4 After fiber glass is reinforced, glass fiber is a high-strength material, which greatly improves the strength of plastics, such as tensile strength, compressive strength and bending strength.
5. After fiber glass reinforcement, due to the addition of glass fiber and other additives, the combustion performance of reinforced plastic decreases a lot, and most materials cannot ignite, which is a kind of flame retardant material.
Disadvantages:
1 After fiber glass reinforcement, it will become opaque due to the addition of glass fiber, which is transparent without glass fiber;
2 After fiber glass reinforced, the toughness of all plastics decreases while the brittleness increases;
3 After fiber glass reinforcement, due to the addition of glass fiber, the melt viscosity of all materials increases, the fluidity becomes worse, and the injection pressure is much higher than that without glass fiber;
4 After fiber glass reinforcement, due to the addition of glass fiber and poor fluidity, in order to normal injection molding, the injection temperature of all reinforced plastics should be increased by 10-30 ℃ than before without glass fiber;
5 Fiber glass enhanced, due to the addition of glass fiber and additives, the hygroscopic performance of enhanced plastic is greatly strengthened, the original pure plastic does not absorb water will become water absorption, therefore, injection should be into drying.
