Silica Sand an overview ScienceDirect Topics

Glass fiber is manufactured from various raw materials, namely, silica sand, alumina, limestone, clay, and boric acid. There are different types of glass fiber, like E-glass and S-glass, depending on the mechanical properties. E-glass has high mechanical properties and it is used in armor applications.
