PRODUCT INFORMATION VD agy 933 S-2 Glass®Yarn 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 933 S-2 Glass yarn is designed to be used in aerospace, defense and recreation applications such as: • Radomes • Leading and trailing edges of aircraft wings 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, these yarns meet the requirements of MIL-Y-114OH specifications. Product Descripti0n 933 S-2 Glass direct sized yarns consist of numerous G-filament (9 microns) continuous glass strands, twisted to form yarns and treated with a thermally stable inorganic sizing for high temperature matrices. Resin C0mpatibility • Polyamide • Phenolic • Polyimide • Bis-Maleimides • Epoxy • Polyetherimide • Polyetheretherketone • Liquid Crystal Polymers • Cyanate Ester 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) Enhanced stiffness Consistent high performance for reliable and durable finished parts Excellent tolerance to damage accumulation S-2 Glass fibers deliver 20% reduction in dielectric constant over E-Glass fibers Long shelf life, good machinability and excellent durability Quick wet-out (penetration of resin into the strand) 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 Delivers 25% more linear-elastic stiffness than conventional glass fiber The ability of composite parts to withstand high levels of tension and flexural fatigue without catastrophic failure Radar transparency Consistent performance and reliability Faster, more efficient processing Processes • Weaving • Braiding The 933 sizing is stable at processing temperatures of 354°C (670°F) Facilitates molding with high temperature thermoplastic matrices, yielding exceptional laminate mechanical properties
