玻璃纤维的抗拉强度约为普通钢筋的10-12倍,相当于优质钢材的2-2.5倍.如何能把玻璃纤维用作结构材料,这个问题首先在苏联得到了解决,这又一次充分的说明社会主义制度的优越性.在我国玻璃纤维已经有不少厂试制出来了,不久的将来,这一工业必然会飞越的发展.因此,如何把它用作结构材料也就成为大家关心的一个问题了.现在我们将苏联的试验做一简单的介绍. 这试验是苏联基辅工艺学院研究的,用水泥混凝土与玻璃纤维结合,来利用玻璃纤维的高强度.用作试验的是500号波特兰水泥及无碱的、直径6-10微米的矽酸硼铝质玻璃纤维,它的强度是18,000-24,000公斤/平方公分,弹性系数为720,000-750,000公斤/平方公分.把90-100 The tensile strength of glass fiber is about 10-12 times that of ordinary steel bar, which is equivalent to 2-2.5 times that of high-quality steel. How can we use glass fiber as a structural material? This problem was first solved in the Soviet Union, and this is once again sufficient. Explain the superiority of the socialist system. Many glass fiber factories in China have been trial-produced. In the near future, this industry will inevitably develop. Therefore, how to use it as a structural material has become a concern for everyone. Problems. Now we will make a brief introduction of Soviet experiments. This experiment was studied by the Kiev Institute of Technology in the Soviet Union. It was cement concrete combined with glass fiber to take advantage of the high strength of glass fiber. The experiment was conducted at 500 Porter. Blue Portland cement and alkali-free, 6-10 μm diameter borosilicate glass fiber, its strength is 18,000-24,000 kg/cm2, and the elasticity coefficient is 720,000-750,000 kg/cm2.
