Title (EN) COMPOSITION FOR HIGH PERFORMANCE GLASS FIBERS AND FIBERS FORMED THEREWITH
(FR) COMPOSITION POUR FIBRES DE VERRE HAUTE PERFORMANCE, ET FIBRES FORMÉES AVEC CETTE COMPOSITION
Abstract:
(EN) A composition for the manufacture of high strength glass fibers suitable for manufacture in both precious metal lined furnaces and refractory lined glass melter is disclosed. The glass composition of the present invention includes 62-68 weight % SiO2, 22-26 weight % Al2O3, 8-15 weight % MgO and 0.1 to 3.0 weight % Li2O. One suitable composition of the present invention includes 64-66.5 weight percent SiO2, 23-24.5 weight percent Al2O3, 9-11 weight percent MgO and 0.3-.35 weight percent Li2O. Another suitable composition includes 66.5 weight percent SiO2, 23.4 weight percent Al2O3, 9.8 weight percent MgO and 0.3 weight percent Li2O. Yet another suitable composition is about 66 weight percent SiO2, about 23 weight percent Al2O3, about 10.5 weight percent MgO and about 0.3 weight percent Li2O. Fibers formed by the present invention are also disclosed. The fibers have a fiberizing temperature of less than 2650° F, a ΔT of at least 25° F. Further, the glass fibers of the present invention typically have a strength in excess of 700 KPSI, in one embodiment, a strength in excess of about 730 KPSI, and, in yet another embodiment, a strength in excess of about 750 KPSI. The glass fibers will typically have a modulus greater than 12.8 MPSI, in one embodiment, greater than about 13MPSI, and, in yet another embodiment, greater than about 13.2 MPSI.
(FR) La présente invention concerne une composition pour la préparation de fibres de verre de haute résistance qui peuvent être adéquatement produites à la fois dans des fours à garniture en métal précieux et des fours de fusion du verre à garniture réfractaire. La composition de verre ci-décrite comprend, en pourcentage pondéral, 62-68 % de SiO2, 22-26 % d'Al2O3, 8-15 % de MgO et 0,1-3,0 % de Li2O. Une composition appropriée comprend, en pourcentage pondéral, 64-66,5 % de SiO2, 23-24,5 % d'Al2O3, 9-11 % de MgO et 0,3-0,35 % de Li2O. Une autre composition appropriée comprend, en pourcentage pondéral, 66,5 % de SiO2, 23,4 % d'Al2O3, 9,8 % de MgO et 0,3 % de Li2O. Encore une autre composition appropriée comprend, en pourcentage pondéral, environ 66 % de SiO2, environ 23 % d'Al2O3, environ 10,5 % de MgO et environ 0,3 % de Li2O. L'invention concerne également des fibres préparées à partir de la composition. Ces fibres ont une température de fibrage inférieure à 2650 °C et un ΔT d'au moins 25 °C. En outre, les fibres de verre ci-décrites ont typiquement une résistance dépassant respectivement 700 kpsi, 730 kpsi ou 750 kpsi dans trois modes de réalisation distincts, et un module respectivement supérieur à 12,8 Mpsi, 13 Mpsi ou 13,2 Mpsi dans trois modes de réalisation distincts.
