This paper is concerned with the creation and the detection of damage in cryogenic composites due to thermo-mechanical loading. The first part deals with cryocycling (cycling between two temperatures) test procedures, that were developed to understand the damage produced in cryogenic composite laminates under thermo-mechanical loading. The second part of the paper deals with the NDE techniques (optical edge examination, X-ray radiography and ultrasonics) used in the characterization of cryogenic composites, with a special emphasis on an ultrasonic NDE technique for a ply-by-ply detection of matrix cracks.
