Patent number: 9878941Abstract: A glass composition including SiO2 in an amount from about 70.0 to about 78.2% by weight, Al2O3 in an amount from about 18.6 to about 26.2% by weight, MgO in an amount from about 3.1 to about 10.7% by weight, CaO in an amount from 0.0 to about 7.6% by weight, Li2O in an amount from about 0.1 to about 5.0% by weight, and Na2O in an amount from 0.0 to about 0.2% by weight is provided. In exemplary embodiments, the glass composition is free or substantially free of B2O3 and fluorine. The glass fibers have a specific strength between about 1.6×106 J/kg and 2.24×106 J/kg and a specific modulus between about 3.3×107 J/kg and 3.7×107 J/kg. Glass fibers formed from the inventive composition possess exceptionally high specific strength and a low density, which make them particularly suitable in applications that require high strength, high stiffness, and low weight, such as in wind blades and aerospace structures.Type: GrantFiled: October 18, 2011Date of Patent: January 30, 2018Assignee: OCV Intellectual Capital, LLCInventors: Douglas Alan Hofmann, Peter B.
