ABSTRACT:
A ballistic armor uses shape memory alloys and novel joining techniques to form a solution from a combination of shape memory metallic alloys (SMA) and ceramic materials. The SMA allows a high amount of strain to be recovered through a low temperature heat treatment. The amount of strain recoverable is much higher than that available through conventional thermal expansion mismatch solutions. Solid state or low temperature bonding methods are used to join the dissimilar materials. This joining technique avoids introducing excessive heat that would cause the SMA to transform before the armor system is assembled.
