Abstract

A new laser based remote NDE method named RAID is described and some selected results are presented in this paper. This system has demonstrated its ability to detect defects in solid laminates; honeycomb/carbon, where defects at the rear have been observed; bonding defects in ceramic and also defects such as cracking in the new carbon foam materials, both of these latter materials have extremely high acoustic attenuation. Additionally the system has recently demonstrated its feasibility to detect and quantify subsurface corrosion in aluminum riveted and bonded structures such as lap joints; to date 5% metal loss has been detected. Defects in other metal structures such as tear straps in airframe fuselages of transport aircraft are rapidly detectable.
