Composite materials tubes are being used in various industrial segments, including the oil and gas industry1. The union between adjacent composite tubes is often accomplished through adhesives, and thus the inspection for flaws in adhesive-bonded joints becomes crucial. In this context, tubes and elbows made of epoxy resin reinforced with glass fiber were assembled with adhesive in the Quick-Lock® 1 configuration forming loops (spools). During the assemblage of these loops, artificial defects (areas without adhesive or disbondings) were inserted in its joints to evaluate the capability of failure detection by shearography. This paper presents and discusses results obtained with shearography. Shearography demonstrated great potential for application in the adhesive-bonded joints inspection, as it detected all defects artificially inserted and also real defects present in the loops joints.
