玻璃钢学名玻璃纤维增强塑料。它是以玻璃纤维及其制品(玻璃布、带、毡、纱等)作为增强材料,以合成树脂作基体材料的一种复合材料。复合材料的概念是指一种材料不能满足使用要求,需要由两种或两种以上的材料复合在一起,组成另一种能满足人们要求的材料,即复合材料。例如,单一种玻璃纤维,虽然强度很高,但纤维间是松散的,只能承受拉力,不能承受弯曲、剪切和压应力,还不易做成固定的几何形状,是松软体。如果用合成树脂把它们粘合在一起,可以做成各种具有固定形状的坚硬制品,既能承受拉应力,又可承受弯曲、压缩和剪切应力。这就组成了玻璃纤维增强的塑料基复合材料。由于其强度相当于钢材,又含有玻璃组分,也具有玻璃那样的色泽、形体、耐腐蚀、电绝缘、隔热等性能,象玻璃那样,历史上形成了这个通俗易懂的名称“玻璃钢”,这个名词是由原国家建筑材料工业部部长赖际发同志于1958 年提出的,由建材系统扩至全国,现在还普遍地采用着。由此可见,玻璃钢的含义就是指玻璃纤维作增强材料、合成树脂作粘结剂的增强塑料,国外称玻璃纤维增强塑料。随着我国玻璃钢事业的发展,作为塑料基的增强材料,已由玻璃纤维扩大到碳纤维、硼纤维、芳纶纤维、氧化铝纤维和碳化硅纤维等,无疑地,这些新型纤维制成的增强塑料,是一些高性能的纤维增强复合材料,再用玻璃钢这个俗称就无法概括了。考虑到历史的由来和发展,通常采用玻璃钢复合材料,这样一个名称就较全面了。

Glass steel glass fiber reinforced plastic. It is a kind of composite material that uses glass fiber and its products(glass cloth, tape, felt, yarn, etc.) as an enhanced material and synthetic resin as a matrix material. The concept of a composite material refers to a material that can not meet the requirements for use and needs to be combined by two or more materials to form another material that can meet people's requirements, namely a composite material. For example, a single type of glass fiber, although its strength is high, is loose between the fibers, can only withstand tension, can not withstand bending, shear and compressive stress, and is not easy to make a fixed geometry, is loose software. If they are bonded together with synthetic resins, they can be made into a variety of rigid products with a fixed shape that can withstand both tensile stress and bending, compression and shear stress. This forms a fiberglass reinforced plastic matrix composite. Because its strength is equivalent to that of steel and it contains glass components, it also has the same color, shape, corrosion resistance, electrical insulation, and thermal insulation as glass. Like glass, this easy-to-understand name "fiberglass" has historically been formed. This term was proposed by the former State Minister of Construction Materials Industry, Comrade Laijifa, in 1958. It was expanded from the building materials system to the whole country and is now widely used. From this we can see that the meaning of fiberglass is to refer to fiberglass as an enhanced material and synthetic resin as an enhanced plastic for binders, which is called fiberglass reinforced plastic abroad. With the development of China's fiberglass industry, as a plastic-based reinforcement material, it has been expanded from glass fiber to carbon fiber, boron fiber, aramid fiber, aluminum oxide fiber and Silicon carbide fiber, etc.. Undoubtedly, these new types of fibers are made of reinforced plastics. It is some high-performance fiber reinforced composites, and the common name of fiberglass can not be summarized. Considering the origin and development of history, FRP composites are usually used, and such a name is more comprehensive.
