Abstract : The patent describes a hyperbaric simulator for evaluating thickness change, stretch-flex change, thermal conductance and other material properties under simulated deep sea pressures down to 1,000 feet. Gas control and instrumentation hardware, testers and pressure chamber equipment necessary for studying the above material properties are incorporated into an integrated facility. The thickness tester includes a lowforce spring-actuated piston which maintains contact with the sample surface as it undergoes thickness changes, the stretch-flex tester monitors the center deflection of a sample when a small pressure differential is applied across the face of the sample, and the thermal conductance tester employs the guarded hot plate system to determine thermal conductance.
