Ultrasonic Techniques for Inspecting Multi-Layer Composite Components
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.
