Abstract
Glass compositions suitable for fiber forming having low levels of LiO and glass fibers having high-modulus are disclosed. The glass composition may include SiOfrom about 59 to about 63 weight percent, AlOfrom about 13.7 to about 16 weight percent, CaO from about 14 to about 16.5 weight percent, MgO from about 6 to about 8.5 weight percent, FeOless than 1 weight percent, and TiOless than 1 weight percent. In some cases, the composition may be substantially free of LiO. In some cases, the composition may include LiO up to 0.5 weight percent. In some cases, REOmay be present in the composition in an amount up to 1.5 weight percent. The glass compositions can be used to form glass fibers which can be incorporated into a variety of other fiber glass products (e.g., strands, rovings, fabrics, etc.) and incorporated into various composites.
