Non-Destructive small defects detection of GFRP laminates using pulsed thermography

Abstract

This work explores the possibility to apply thermographic technique as non destructive test to control glass fiber reinforced polymers having artificial defects. Three symmetrical composite panels reinforced with fiberglass (unidirectional E type fiberglass and epoxy resin) were realized through hand lay‐up and artificial inter‐laminar delaminations of various geometry were introduced at different depths. Several thermal stimulation procedures with different ways to consider the defects in the specimens enable to optimize the thermographic technique, by solving some initial problems related to the experimental set -up and issues. Above all, the minimum requirements for defect which can be revealed trough pulsed thermography have been established, according to present experiences. The importance of geometric and thermo-physic characteristics of the defect related to the material in which it is inserted has been observed, as well as the surface conditions of the observed laminate faces
