Damage assessment of thin woven composite subjected to quasi-static tensile loading using infrared thermography

Abstract : In this study, an experimental approach for characterizing damage evolution on thin glass/epoxy woven composite using infrared thermography is presented. First, the damage scenario is investigated combining thermal field measurements and optical microscopic observations. Then, the surface temperature images are used to evaluate the dissipative heat source using the local heat diffusion equation, in the case of thin rectangular sample. Afterwards, a 2D spatial cartography of damage is obtained for different strain level, as well as an estimation of the energy release rate induced by transverse yarn microcracking. Finally the relevance of those experimental results is discussed by referring to the literature dealing with fracture toughness of woven composite.
