it was found that zinc oxide is a modifier that effectively increases the modulus of aluminate and silicate glass fibers. glass fibers having a higher fiber modulus than that of s-glass were prepared by modifying aluminate and silicate composition with 5-25 mol zno under conventional glass-forming conditions by melting the mixed oxide powders above the liquidus. the highest fiber modulus obtained in the zno-modified aluminate system (44cao-30al//2o//3-10zno-5mgo-5li//2o-4sio//2) was 1.44 $multiplied by$ that of s-glass, but a new drawing process would be required the highest modulus obtained in the silicate system (46.8sio//2- 16.9zno-12.1cao- 11.8mgo-5.3tio//2-5.3li//2o-0.9zro//2-0.9ceo-0.01 fe//2o//3) was 1.20 $multiplied by$ that of s-glass and no new process is required.
