Abstract
When observing or describing the damage state in a composite material, often only Young’s modulus or residual deformation are considered. Generally, however, the Poisson’s ratio is more sensitive to damage. Rather than observing the Poisson’s ratio as function of crack density, this article studies the evolution of the Poisson’s ratio as function of the longitudinal strain, which results in a peculiar shape. First, multiple experiments are discussed to determine whether this behaviour is due to the material or to the used sensor. Next, a theoretical explanation, based on the relief of thermal stresses, is presented and validated for the peculiar evolution of the Poisson’s ratio as function of the longitudinal strain. The material used for this study is a carbon fabric-reinforced Polyphenylene Sulphide.
