Abstract
A glass composition including SiO2 in an amount from 74.5 to 80.0% by weight, Al2O3 in an amount from 5.0 to 9.5%>> by weight, MgO in an amount from 8.75 to 14.75% by weight, CaO in an amount from 0.0 to 3.0% by weight, Li2O in an amount from 2.0 to 3.25% by weight, Na2O in an amount from 0.0 to 2.0% by weight is provided. Glass fibers formed from the inventive composition may be used in applications that require high strength, high stiffness, and low weight. Such applications include woven fabrics for use in forming wind blades, armor plating, and aerospace structures.
