Abstract
The feasibility of using pulse phase thermography (PPT) to identify defects in adhesively bonded joints is assessed. Artificial defects created in solid materials are successfully identified using the phase images produced by PPT. Contaminants typical of those found in the manufacturing environment have been used to recreate kissing defects in joints in polymer composite materials constructed using a single shot process and by using secondary bonding. It is shown that PPT has the potential to identify kissing defects.
