Abstract:

A novel device for the nondestructive testing of glass clothepoxy composites is discussed. A thermal comparator is designed to detect nonconformities in the thermal properties of the composites. Principal advantages of the instrument are its simplicity of design and operation and its very modest cost. A series of test results for metallic and nonmetallic inclusion detection is presented. The applicability to thickness determinations is examined, and several promising uses of the device are suggested.
