Abstract
An armor system with a lightweight armored panel manufactured as a multi-material structure having a multiple of layers including a hard ballistic material layer of a Ceramic/CMC (Ceramic Matrix Composite) hybrid armor material capable of defeating ballistic threats. The monolithic ceramic layer includes a surface enhancement to the expected projectile impact face of a minimal weight yet which provides significant ballistic performance improvement.
Claims18
A hard ballistic material comprising:
- a monolithic ceramic layer;
- a Diamond-Like Carbon (DLC) coating applied to a front face of said monolithic ceramic layer;
- and
- a rear face Ceramic Matrix Composite (CMC) layer continuously bonded to a rear face of said monolithic ceramic layer to provide a close thermal expansion match of said monolithic ceramic layer and said Ceramic Matrix Composite (CMC) layer.
