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