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: SiO262-72% Al2O3 2-10% CaO 7-20% MgO1-7% Na2O + K2O + Li2O 10-14.5% Li2O0-2% BaO + SrO + ZnO0-4% B2O30-4% F20-2% 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.
