<p>The invention relates to glass strands especially for the production of composites having an organic and/or inorganic matrix, the composition of which strands comprises the following constituents in the limits defined below, expressed as percentages by weight: SiO2 50-65% Al2O3 12-23% SiO2 + Al2O3 >79% CaO 1-10% MgO 6-12% Li2O 1-3%, preferably 1-2% BaO + SrO 0-3% B2O3 0-3% TiO2 0-3% Na2O + K2O <2% F2 0-1% Fe2O3 <1%. These strands are made of a glass offering an excellent compromise between its mechanical properties, represented by the specific Young's modulus, and its melting and fiberizing conditions.</p> |
