High-silica fibers and fabrics are flexible materials that are similar in appearance to—and produced from—fiberglass. The fiberglass, with a silica content of 65%, is subjected to a hot-acid treatment that removes virtually all of the impurities

The high mechanical strengths, high moduli of elasticity, and low densities of fibers made from such substances as carbon, boron, and glass, when combined with the toughness of various epoxy, polyester, and polyimide resins, produce a class of

By using composite technology, it is now possible to tailor-make structural materials for specific applications. (See Appendix B.)
