玻璃钢的知识点
The knowledge point of FRP
玻璃钢，即纤维强化塑料，一般指用玻璃纤维增强不饱和聚脂、环氧树脂与酚醛树脂基体。以玻璃纤维或其制品作增强材料的增强塑料，称为玻璃纤维增强塑料，或称玻璃钢。由于所使用的树脂品种不同，因此有聚酯玻璃钢、环氧玻璃钢、酚醛玻璃钢之称。质轻而硬，不导电，机械强度高，回收利用少，耐腐蚀。可以代替钢材制造机器零件和汽车、船舶外壳等。缺陷较少又较小，断裂应变约为千分之三十以内，是脆性材料，易损伤、断裂和受到腐蚀。基体相对于纤维来说，强度、模量都要低很多，但可以经受住大的应变，往往具有粘弹性和弹塑性，是韧性材料。
FRP, or fiber reinforced plastics, generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics, which are made from glass fiber or their products, are called glass fiber reinforced plastics, or FRP. Because of the different resin varieties used, it is called polyester FRP, epoxy FRP and phenolic FRP. It is light and hard, non conductive, high mechanical strength, less recycling and corrosion resistance. It can replace steel for manufacturing machine parts, automobile and ship case. The defect is less and smaller. The fracture strain is less than 30/1000. It is brittle material, easy to damage, fracture and corrode. The strength and modulus of matrix are much lower than those of fibers, but they can withstand large strains, often viscoelastic and elastoplastic. They are tough materials.
