GLASS STRANDS, AND ORGANIC AND/OR INORGANIC MATRIX COMPOSITES CONTAINING SAID STRANDS

摘要

The invention relates to glass yarns intended in particular for production of organic matrix composites and / inorganic composition whose composition comprises the following constituents in the defined below, expressed in percentages by weight: SiO2 50 -65% Al2O3 12 -23% CaO 1-10% MgO 6-12% Li2O1- 3%, preferably 1-2% BaO + SrO 0 -3% B2O3 0 -3% TiO2 0 -3% Na2O + K2O 2% F2 0-1% Fe2O3 1%. These threads are made of a glass offering an excellent compromise between its mechanical properties represented by the Young's modulus specific and its conditions of merger and fiber drawing.
