Evaluation of Large Carbon Composite Cones Using Thermal Transducer

A series of nondestructive tests utilizing a new thermal detector, known as a thermal transducer, has been conducted on a group of large carbon-carbon test cones. A description of the operating principles and special fixtures required to use the thermal transducer is provided. Results of thermal and other standard NDT methods are compared and recommendations regarding the capabilities of the thermal transducer are made.
