PRODUCT INFORMATION 449 S-2 Glass® Roving High-Strength Solutions for Your Toughest Reinforcement Challenges AGY’s S-2 Glass® high-strength bers are specically designed to meet your most demanding performance processing and cost requirements. AGY’s global network of people and facilities are ready to help you develop innovative solutions to your most difcult reinforcement challenges. Product Application 449 S-2 Glass roving is designed to be used in aerospace, defense and recreation applications such as: • Helicopter blades • Golf shafts • Pressure vessels • Aircraft ooring • Aircraft fuel tanks Product Solutions S-2 Glass bers offer a unique combination of properties: strength, impact resistance, stiffness, radar transparency and temperature and fatigue resistance. Compared with other reinforcing materials, S-2 Glass bers weigh less than conventional glass ber and deliver better cost performance than aramid and carbon bers. In addition, they meet the requirements of MIL-R-60346 Type IV, Class 1 specications. Black Hawk Helicopter Blades S-2 Glass Roving S-2 Glass ber offers signicantly more strength than conventional glass ber: 85% more tensile strength in resin impregnated strands Consistent high performance for reliable and durable nished parts Better ber toughness, modulus of resilience and impact deformation than conventional glass ber Improved impact capabilities to nished parts and higher composites durability and damaged tolerance Product Description 449 S-2 Glass roving consists of numerous G-lament (9 micron) continuous glass strands, gathered without mechanical twist and treated with an amino-silane, epoxycompatible sizing. Softening point: 1056°C (1932°F) Annealing point: 816°C (1500°F) Strain point: 766°C (1410°F) Greater ber tensile strength and stability at elevated temperatures in thermoset and thermoplastic applications Enhanced stiffness Resin Compatibility • Epoxy (amine-cured) • Urethane (selected) Delivers 25% more linear-elastic stiffness than conventional glass ber Excellent tolerance to damage accumulation The ability of composite parts to withstand high levels of tension and exural fatigue without catastrophic failure Processes • Weaving • Hand Lay-up • Uni-Directional Pre-Impregnation • Filament Winding • Contact Molding • Compression Molding S-2 Glass bers deliver 20% reduction Radar transparency in dielectric constant over E-Glass bers Long shelf life, good machinability and excellent durability Consistent performance and reliability Quick wet-out (penetration of resin into the strand) Faster, more efcient processing
