One of the first applications of composite armor was on CAV 100 vehicles used by the United Nations High Commissioner for Refugees to protect workers aiding civilians fleeing combat zones. Composite armor was made by high-pressure compression molding multiple layers of high-strength glass in epoxy resin. An important performance benefit was the reduction of spall, the deadly fragments that can come from the back side of metal armor when hit by a projectile. Today, military vehicle manufacturers are exploiting the ability of composites to combine structure and protection in an integrated solution.
