PRODUCT INFORMATION VD agy 463 S-2 Glass® Roving strength in materials Hegnhf0SSetn^SC0hlaU|^ie0nngSeS0rY0Url'0U9heSt AGY's S-2 Glass® high-strength fibers are specifically 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 difficult reinforcement challenges. Product Applicati0n 463 S-2 Glass roving is designed to be used in aerospace, defense and recreation applications such as: • Pressure vessels • Ballistic armor • Aircraft flooring Product S0luti0ns S-2 Glass fibers 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 fibers weigh less than conventional glass fiber and deliver better cost performance than aramid and carbon fibers. In addition, they meet the requirements of MIL-R-60346Type IV, Class 1 specifications. Product Descripti0n 463 S-2 Glass roving consists of numerous G-filament (9 micron) continuous glass strands, gathered without mechanical twist and treated with an epoxy-silane sizing. Cougar MRAP Military Vehicle S-2 Glass fiber offers significantly more strength than conventional glass fiber: 85% more tensile strength in resin impregnated strands Better fiber toughness, modulus of resilience and impact deformation than conventional glass fiber Softening point: 1056°C (1932°F) Annealing point: 816°C (1500°F) Strain point: 766°C (1410°F) Consistent high performance for reliable and durable finished parts Improved impact capabilities to finished parts and higher composites durability and damaged tolerance Greater fiber tensile strength and stability at elevated temperatures in thermoset and thermoplastic applications Enhanced stiffness Resin C0mpatibility • Epoxy (anhydride-cured) Delivers 25% more linear-elastic stiffness than conventional glass fiber Processes • Weaving • Hand Lay-up • Uni-Directional Pre-Impregnation • Filament Winding • Contact Molding • Compression Molding Excellent tolerance to damage accumulation The ability of composite parts to withstand high levels of tension and flexural fatigue without catastrophic failure S-2 Glass fibers deliver 20% reduction Radar transparency in dielectric constant over E-Glass fibers Long shelf life, good machinability and Consistent performance and excellent durability reliability Quick wet-out (penetration of resin into Faster, more efficient processing the strand)
