Abstract
A shape memory alloy composite fabric and a method of use is provided in underwater pressure vessels and as flexible joints in atmospheric diving suits. The atmospheric diving suit internal pressure is one atmosphere for underwater transit to and from an underwater work site. During operations at a work site, the shape memory alloy joints transform to a martensite phase and enable greater flexibility while the pressure in the atmospheric diving suit equalizes with ambient depth pressure.
