Inspection of Carbon/Epoxy and Aluminum Honeycomb Paraboloidal Components by HNDT

Abstract

This paper discusses examples of the use of the double-exposure method to inspect carbon/epoxy skin and aluminum honeycomb core paraboidal components. Laser holographic technology can detect separation style and closely attached style glue-loss defects, but its sensitivity in detecting the closely attached style defects is lower than its sensitivity in detecting the separation style defects. Laser holographic technology has the capacity of detecting confused areas within the honeycomb core, but the results are not so good as with direct X-ray observation. Keywords: Lithographic plates; Defects materials; Translations; China; Chinese language.
