Abstract: A high-intensity and high-modulus glass fiber is provided. Said fiber is produced by improving the processes, components and proportion of conventional E-glass production process and apparatus. The fiber contains 13% CaO at most, no boron and fluorine, meanwhile ZrO2 and Li2O is first added, B2O3 is first removed, and SO3 is added. The intensity and the modulus of the fiber are slightly lower than those of S-glass or T-glass, but obviously higher than those of E-glass and ECR-glass which are highly produced and widely used or other boron-free glass such as Advantex glass. Besides the intensity, modulus and fatigue resistance, said fiber has obvious advantages over E-glass in heat, acid and alkali resistance. The glass fiber roving made from said fiber has 22% higher tensile strength and 11˜15.7% higher modulus than those of E-glass, and has 16% higher tensile strength and 5˜6% higher modulus than those of ECR-glass.
