Long fiber thermoplastics (LFTs) offer benefits to design engineers seeking a material that provides exceptional strength, yet requires lightweight properties. DESIGN SUPPORT Designing your application for long fiber thermoplastics, regardless of material familiarity, requires an assessment of a wide array of inputs to achieve the optimal geometry. • Fiber reinforcement percentage (ranging from 20–70% fiber content, by weight) • Additive technologies (color, UV enhancement, flame retardancy, heat stabilization, etc.)

TOUGH ENOUGH TO PROTECT THE POWER GRID MODULAR BALLISTIC PROTECTION MADE POSSIBLE WITH COMPOSITES THE CHALLENGE Recent attacks on U.S. electrical substations across the country provide stark reminders that our nation’s power supply remains a primary target for criminals focused on harming our country and security.1 The call to action is evident: we must continually improve the physical and technological infrastructure protection of our nation’s energy supply. THE SOLUTION Ballistic-resistant panels made with fiber-reinforced polymer (FRP) composites offer key properties that enable Southern States to meet its customers’ critical needs. THE IMPACT Southern States’ ballistic-resistant solutions incorporate three layers of uniquely formulated GlasArmor composite panels to achieve Underwriters Laboratories (UL) Level 8 protection.
