AN INTRODUCTION OF A TWIST-FREE GLASS ROVING AND A HIGH IMPACT RESISTANT LIGHT WEIGHT FABRIC FOR THERMOSET APPLICATIONS

摘要

FliteStrand® S is the designation of a new generation of aerospace high performance glass fiberrnreinforcements that have been specifically designed to meet the rigorous demands of compositernaerospace applications, which require high strength, light weight, impact resistance, andrndurability. Initially consisting of only UD rovings, the product portfolio has been expanded torninclude high-performance fabrics.rnWithin the FliteStrand® S product portfolio, Owens Corning has developed two S-glass productsrnthat substantially advance the state of the art in thermoset composite applications. The first is arnsingle end, completely twist-free roving that can increase unidirectional (UD) tensile strength byrnup to 15% and lower minimum achievable fiber areal weight to below 120gsm. The second is arnfamily of direct-sized fabrics that can increase laminate impact loading by more than 25% andrnlaminate toughness by more than 50% in a variety of resins. Additional benefits includernpotentially higher mechanical properties versus greige and re-finished fabrics.
