Quartz fibers are very pure, fused silica glass fibers composed of over 99.95% silicon dioxide.[1] The fibers are primarily used to reinforce a larger group of materials called composite materials.[1] [2]
Quartz fibers are long-continous fibers and are produced from continous strands of quartz of either 120 or 240 individual filaments that are twisted into heavier fibers.[1] Quartz fibers have high temperature strength, tensile strength, chemical stability, hydrophobicity, and electrical resistivivity.[1] [3] [4] The fibers also have a lower density, higher stiffness, and require greater elongation to break compared to typical glass fibers such as E-Glass, making the quartz fibers candidates for improving the mechanical abilties of materials.[5]
Quartz fibers have become a focal point of many researchers involved in chemical engineering, composite materials, and polymer science. Some of the prominant uses of these fibers include fabric yarns, electrical insulators, increasing the strength and temperature resistance of fabrics, improving the floating capability of boats, and enhancing materials in the aerospace industry.[1] [4] [5] These fibers cost far more than ordinary glass fibers, reaching up to $150 per pound for the more pure forms. The high quality quartz needed for quartz fiber is very rare, mainly mined in Brazil.[2]
