Abstract: front page image
(EN)The present invention provides a glass fiber fabric suitable as a reinforcement material for a printed wiring board, and the glass fiber thereof. This glass fiber comprises, based on the total weight of the constituents, 56.0-62.5 weight% of SiO2, 15.5-24.5 weight% of Al2O3, 0.1-4.0 weight% of CaO, 6.0-14.0 weight% of MgO, 3.0-9.0 weight% of ZnO, and 0.5-4.5 weight% of B2O3, the total content of SiO2, Al2O3, CaO, MgO, ZnO, and B2O3 being 99.0 weight% or more, the total content of ZnO and B2O3 being 4.5-13.0 weight%, and the weight ratio of MgO with respect to CaO (MgO/Cao) being 3.0 or more. This glass fiber has both a high modulus and a low coefficient of linear expansion.
(FR)La présente invention concerne un tissu de fibre de verre approprié en tant que matière de renforcement pour une carte imprimée, et la fibre de verre de ce tissu. Cette fibre de verre comprend, sur la base du poids total des constituants, 56,0-62,5 % en poids de SiO2, 15,5-24,5 % en poids d'Al2O3, 0,1-4,0 % en poids de CaO, 6,0-14,0 % en poids de MgO, 3,0-9,0 % en poids de ZnO et 0,5-4,5 % en poids de B2O3, la teneur totale de SiO2, Al2O3, CaO, MgO, ZnO et B2O3 étant de 99,0 % en poids ou plus, la teneur totale de ZnO et B2O3 étant de 4,5-13,0 % en poids et le rapport en poids de MgO par rapport à CaO (MgO/CaO) étant de 3,0 ou plus. Cette fibre de verre possède à la fois un module élevé et un faible coefficient de dilatation linéaire.
