Vehicle Armor Composite System (VACS) Composite armor solutions for a wide variety of vehicle systems made with glass fiber manufactured by AGY and processed by proven industry partners. The VACS system has a composite protection solution to meet your needs. Improved Ballistic Performance for Your Most Severe Ballistic Threats Featherlight S-2 Glass® roving is designed to meet your toughest ballistic protection applications with weight savings of approximately 5% over standard S-2 Glass roving solutions. S-2 Glass has set the standard for highstrength glass fiber reinforcements for over 25 years, with a 40% higher strength than conventional glass fiber roving, and a 20% higher modulus. The improvement made by Featherlight is a step change progression that will allow armor designers to make significant reduction in weight and increase in ballistic protection. The Featherlight technology is a result of advanced process improvements that allow for the production of S-2 Glass filaments with increased tensile strength. The result is a composite armor that protects at the same level with a 5% lighter panel. Because Featherlight is a fiber enhancement, it can be manufactured in any of the standard S-2 Glass fiber formats. Designed to work seamlessly in AGY’s HJ1 system, users will find that the Featherlight fibers process identical to the matching S-2 Glass fiber product. The advantages of Featherlight become apparent when the panels are subject to a ballistic event. The Featherlight roving is currently available in an epoxy compatible sizing that it is appropriate for ballistic applications in phenolic and thermoplastic resins. It can also be custom manufactured with the full range of standard S-2 Glass roving sizings as warranted by specific programs.
