    Publication number: 20070087139
    Abstract: The invention relates to glass reinforcing yams, the composition of which comprises the following constituents, within the limits defined below, expressed in percentages by weight: SiO2 50-65% Al2O3 12-20% CaO 13-16% MgO ?6-12% B2O3 0-3% TiO2 0-3% Na2O + K2O <2% F2 0-1% Fe2O3 <1. These yarns 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.
