玻璃钢是一种复合材料。它是以玻璃纤维及其制品为增强材料,以热固性和热塑性树脂为基体,通过一定的成型工艺制成的一种复合体,国外称它为玻璃纤维增强塑料。我国于1958年开始发展,当时为了代替钢铁,故形象地称为“玻璃钢”。玻璃钢具有重量轻、强度高、耐腐蚀、电绝缘、耐烧蚀、传热慢、隔音、防水、易着色、能透过电磁波,性能及形体可设计性好以及成型制造简便等优点,是经济建设和国防建设不可缺少的重要材料之一。玻璃钢具有不均匀性和各向异性的特点。
FRP is a composite material. It is based on glass fiber and its products as a reinforcing material, thermosetting and thermoplastic resin as the matrix, through a certain molding process made of a complex, known abroad as a glass fiber reinforced plastic. In 1958, China began to develop. In order to replace steel, it was vividly called “FRP.” Glass fiber reinforced plastics have the advantages of light weight, high strength, corrosion resistance, electrical insulation, resistance to ablation, slow heat transfer, sound insulation, waterproof, easy coloring, electromagnetic wave transmission, good performance and body designability, and ease of molding and manufacturing. One of the indispensable important materials for construction and national defense construction. FRP has the characteristics of non-uniformity and anisotropy.
