Resumo: The objective of the present study is to apply digital radiography (DR) and computed microtomography (microCT) techniques to the inspection of laminated pipe Joints in polymeric composite material reinforced by fiberglass. The study comprises a structural assessment, defect characterization and void distribution of each sample. Non-destructive X-ray testing is increasingly present in composite material analyses and has advantages over other laboratory techniques since it is non-invasive and allows for the 2D/3D visualization of the inner structures without previous preparation. The results showed that the techniques detected the defects inserted. The digital radiography made an extension defect measurement possible. The microCT volumetrically quantified these defects as well as the reinforcement and matrix layers.
