Abstract
Composition and process for the preparation of high temperature stable continuous glass fibers with an upper temperature use limit of 2300.degree. F. are provided. The compositional formulation, in mole percent, is 62-85% SiO.sub.2, 10-20% Al.sub.2 O.sub.3, 5-15% MgO, 0.5-5% TiO.sub.x, and 0-5% ZrO.sub.2. The continuous fibers are prepared by an economical direct melt method, and demonstrate high tensile strength, high Young's modulus, and low linear thermal shrinkage characteristics. Friction pads containing these high temperature stable continuous glass fibers are also provided.
