一、国内外金属纤维发展现状和水平金属纤维是一种新型实用工程材料,早在本世纪廿年代,国外一些工业发达的国家就开始研究金属纤维,并用来制造钢纤维混凝土,试图取代部份钢筋混凝土。特别是40年代后,由于军事工程的需要,又有不少国家相继进行钢纤维的研究,但进展都不快。以后随着各国工业的发展,钢纤维制造技术的突破,钢纤维价格有较大幅度的降低,以 First, the current status and level of metal fiber development at home and abroad Metal fiber is a new type of practical engineering materials, as early as the 20th century, some foreign countries developed industrial countries began to study the metal fiber, and used to manufacture steel fiber concrete, trying to replace some RC. Especially after the 1940s, due to the needs of military engineering, many countries have conducted research on steel fibers in succession, but the progress is not fast. With the development of industries in various countries and the breakthrough of steel fiber manufacturing technology, the price of steel fiber has been greatly reduced in the future
