  • Glass strands with low alumina content capable of reinforcing organic and/or inorganic materials
    Patent number: 8367571
    Abstract: The invention relates to reinforcing glass strands, the composition of which comprises the following constituents within the limits defined below expressed as percentages by weight: SiO2 62-72% Al2O3 ?2-10% CaO ?7-20% MgO 1-7% Na2O + K2O + Li2O ??10-14.5% Li2O 0-2% BaO + SrO + ZnO 0-4% B2O3 0-4% F2 0-2% As2O3 ??0-0.15% These strands are composed of a low-cost glass offering an excellent compromise between the mechanical properties represented by the tensile strength and the fiberizing conditions. The invention also relates to the composites based on organic and/or inorganic material(s) and the aforementioned glass strands.
