Glass batch compositions for the formation of high-modulus, and high-strength glass fibers as well as fibers suitable for use as textile and reinforcements are disclosed. Fibers formed of the composition are especially suitable for use in high-strength, low-weight applications such as windmill blades and high strength and modulus applications where strength and stiffness are required in the composite. The glass composition is up to about 70.5 weight % SiO2, about 24.5 weight % Al2O3, about 22 weight % alkaline earth oxides and may include small amounts o...
We claim: 1. A glass fiber formed from a batch composition, comprising: about 60.5 to about 70.5 weight percent SiO2; about 10 to about 24.5 weight percent Al2O3; about 15 to about 20 weight percent alkaline earth oxide, 5 to 11.33 weight percent of said alkaline earth oxide being MgO; about 0 to about 3 weight percent ZrO2; and about 0 to about 3 weight percent alkali metal oxide. 2. The glass fiber of claim 1, wherein said glass has a fiberizing temperature of less than about 2650° F., and a ΔT at least about 80° F. 3. The glass f...
