Abstract
A glass composition is provided that includes about 55.0 to 60.4% by weight SiO, about 19.0 to 25.0% by weight AlO, about 8.0 to 15.0% by weight MgO, about 7 to 12.0% by weight CaO, less than 0.5% by weight LiO, 0.0 to about 1.0% by weight NaO, and 0 to about 1.5% by weight TiO. The glass composition has a fiberizing temperature of no greater than about 2,500° F. Glass fibers formed from the inventive composition may be used in applications that require high stiffness, and low weight. Such applications include woven fabrics for use in forming wind blades and aerospace structures.
