  • Oxynitride glass fibers
    Patent number: 4609631
    Abstract: This invention relates to the production of high elastic modulus, high strength, corrosion-resistant oxynitride glass fibers for improved fiber-reinforced composites. The incorporation of nitrogen into silicon-yttrium-aluminum oxide glasses enhances the properties of bulk glass. This invention is the first demonstration that such glasses can be made into fibers. The addition of nitrogen to practically any oxide glass fiber composition will produce improvements in properties similar to those shown for the silicon-yttrium-aluminum system.
