Abstract

The US Army is evaluating composite materials for use in armored vehicles. Such materials exhibit structural and ballistic characteristics that meet or exceed those of conventional armor at a significant savings in weight. However, to provide comparable properties multi-layer structures must be considered. Proposed armored vehicles might consist of an S-2 glass laminate to meet structural requirements, ceramic tile for ballistic protection, and additional layers for signature management. Both pre-service and in-service inspections will be required to establish the serviceability and survivability of these vehicles.
