Abstract

The analysis of innovative materials and processes stands at the frontier of a series of wide-ranging scientific problems and poses stimulating challenges from a scientific as well as technological point of view, by virtue of its connection with various industrial sectors, such as aerospace and aeronautics. In recent years, composite materials have found numerous applications due to their mechanical characteristics and properties, representing the evolution of materials science and technologies by fusing within them the best characteristics of multiple materials. The present work is focused on the characterization of composite materials, using non-destructive techniques (NDT), to check different kinds of defects eventually present for a quality control of the object under observation. Shearography and thermography are used as nondestructive methods. The former, is an optical interferometric method for the detection of surface or sub-surface defects, the latter is a diagnostic technique that, by measuring the infrared radiation emitted by a body, allows to determine its surface temperature and to understand the health status of the investigated object. The results of the shearography technique, including, are complementary to thermographic techniques and allow us to have a complete characterization of the object. Their use offers advantages related to visualization and testing of end products, as well as the noncontact nature, nondestructive and areal working principle, rapid response, high sensitivity, resolution, and accuracy.
