Diagnostic methods defects detection in joints bonded composite materials

Abstract

During the connection composite materials using glue weld there is a problem with a homogeneous distribution of the adhesive layer on the surface of the element, resulting in the formation of defects in the structure of the weld and reduce the active surface of the impact of adhesion forces the coupled material. There is the need to control the quality of the connection between the glued surfaces. The use of non-contact diagnostic methods enables the analysis of a larger area of the test which determines the efÞ cient process quality control. Compared the methods of detection of defects of bonded joints using active thermography with different excitations types with tomographic imaging. Analysis of diagnostic methods made it possible to speed up the process for Quality Control of welds for the group of materials.
