Abstract

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
