Composite Armored Vehicle

1
Composite Armored Vehicle
Very difficult to detect internal damage by
conventional methods of inspection

• limit in thickness
• hard to inspect multi-layered property materials

multi-layered composite armor

Objective
develop a built-in smart sensory system
- to detect damage due to service loading
