<p>Glass batch compositions for the formation of biosoluble, controlled lifetime glass fibers are disclosed. The glass compositions contain from about 50 to about 60% by weight SiO2, from about 10 to about 20% by weight Al2O3, from about 2 to about 10% by weight CaO, from 0 to about 4% by weight MgO, from about 10 to about 20% by weight Na2O, from about 3 to about 15% by weight K2O, and 0 to about 2% by weight Li2O. Additionally, the glass composition may have a Na2O/ Na2O+K2O ratio in the glass composition is between 0.5 and 0.8. Also, the glass compositions may have an R2O-Al2O3 value between 5 and 16. The biosoluble fibers have mechanical properties close to conventional, non-soluble glass fibers, have a low hydrolytic strength, and are easily fiberized. The glass fiber may be used with a biosoluble matrix resin to form a biodegradable reinforced composite.</p> |
