在运輸及其它一切国民經济部門中,应日益广泛地采用塑料。尤其对大限界的承载结构,采用坡璃鋼和泡沬塑料有着特殊的意义。因为玻璃銅具有此重小、强度大、耐腐性强和传音系数低等优点。并且在生产上不需要大量的准备費用。加里宁车辆厂为了研究铁路运输所用的玻璃鋼性能,会装备了两辆在国内运用的車辆。 In transport and all other sectors of the national economy, plastic should be used more and more widely. In particular, the load-bearing structure of the big boundary, the use of glass fiber reinforced plastic and bubble has a special significance. Because the glass of copper with this small, strong, corrosion resistance and low acoustic coefficient and other advantages. And in the production does not require a lot of preparation costs. Kalinin Vehicle Works In order to study the performance of FRP used in railway transport, it will be equipped with two vehicles that are used domestically.
