The increasing use of fibre reinforced composite materials in structural components, mainly in the aircraft industry has induced manufacturers to acquire appropriate non destructive testing means. Then the necessity to manufacture with larger production rate and tighter quality control requires inspection techniques having higher speed and finer resolution with more accuracy and intelligence than the conventionnal one's used today, namely ultrasonics and X - radiography. A large assessment program has been carried out in order to demonstrate the applicability and reliability of infrared thermography as a method for the inspection of composite and bonded materials.The technique has been developed for an industrial utilization and to specify the systems required for its application. The developments undertaken and the results we have obtained in the final stage of the program are presented.
