Abstract

To study the mechanical behavior of CFRP composites, two methods of damage monitoring are coupled: the acoustic emission (AE) and the infrared thermography (IT). Several studies on the coupling of these two techniques have shown, for example, that it is possible to determine the fatigue strength of ceramic matrix composites under fatigue loading [1]. Other authors have shown the link between the temperature variation and the acoustic parameters evolution (like energy and the number of signals) during fatigue tests on epoxy glass composites [2] and on metallic materials [3]. The similarity of these studies concerns the kind of loading used: a cyclic loading. The aim of this study is to be able to improve the understanding and the characterization of damage mechanisms of unidirectional CFRP composites by coupling acoustic emission and infrared thermography. Besides, damage behavior of CFRP composites samples under static and cyclic loadings are compared.
