| 摘要 |
The invention relates to glass strands, particularly for producing organic and/or inorganic matrix composites, the composition of which contains the following components within the limits hereafter defined and expressed in weight percent: SiO2 50-65%, Al2O3 12-23%, 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 0-1%, Fe2O3 <1%. Said strands comprise a glass offering an excellent compromise between the mechanical properties thereof, represented by the specific Young's modulus, and the fusion and fiber forming conditions thereof. |
