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 a refractory lined glass melter is disclosed. The glass composition of the present invention includes 64-75 weight % SiO2, 16-24 weight % Al2O3, 8-11 weight % MgO and 0.25 to 3.0 weight % R2O where R2O is the sum of Li2O and Na2O. A preferred composition of the present invention includes 64-75 weight % SiO2, 16-24 weight % Al2O3, 8-11 weight % MgO and 0.25 to 3.0 weight % Li2O. Another preferred composition includes 68-69 weight percent SiO2, 20-22 weight percent Al2O3, 9-10 weight percent MgO and 1-3 weight percent Li2O. By using oxide based refractory lined furnaces the cost of production of glass fibers is substantially reduced in comparison with the cost of fibers using a platinum lined melting furnace. Fibers formed by the present invention are also disclosed. The fibers have a fiberizing temperature of less than 2650° F (1454 °C), a ΔT of at least 80° F (44.44 °C). Further, the glass fibers have a strength in excess of 680 KPSI, preferably a strength in excess of about 700 KPSI, and most preferably a strength in excess of about 730 KPSI. The glass fibers will desirably have a modulus greater than 12.0 MPSI, preferably greater than about 12.18 MPSI, and most preferably greater than about 12.7 MPSI.
(FR) La présente invention concerne une composition pour la préparation de fibres de verre de haute résistance qui peuvent être adéquatement produites dans un four de fusion du verre à garniture réfractaire. La composition de verre ci-décrite comprend, en pourcentage pondéral, 64-75 % de SiO2, 16-24 % d'Al2O3, 8-11 % de MgO et 0,25-3,0 % de R2O, où R2O est la somme de Li2O et Na2O. Une composition préférée comprend, en pourcentage pondéral, 64-75 % de SiO2, 16-24 % d'Al2O3, 8-11 % de MgO et 0,25-3,0 % de Li2O. Une autre composition préférée comprend, en pourcentage pondéral, 68-69 % de SiO2, 20-22 % d'Al2O3, 9-10 % de MgO et 1-3 % de Li2O. En utilisant un four à garniture réfractaire à base d'oxyde, le coût de production des fibres de verre est sensiblement réduit par rapport au coût des fibres produites dans un four de fusion à garniture au platine. L'invention concerne également des fibres préparées à partir de la composition. Ces fibres ont une température de fibrage inférieure à 2650 °C (1454 °C) et un ΔT d'au moins 80 °F (44,44 °C). En outre, les fibres de verre ci-décrites ont une résistance dépassant 680 kpsi, de préférence 700 kpsi, idéalement 730 kpsi, et un module supérieur à 12,0 Mpsi, de préférence 12,18 Mpsi, idéalement 12,7 Mpsi.
