Influence of Hydrothermal Ageing on the Residual Stresses and Mechanical Behavior of Carbon/Epoxy Composite Laminates
Résumé
In this work, the residual stresses for composite laminates [02/θ2]S determined by means of the incremental hole-drilling method with a formula to express the relationship between the residual stresses and the relaxed strains around the drilled hole. Then the ageing tests related to hydrothermal condition are carried out to analyze the influence on the residual stress redistributions and also on the mechanical behaviors of the carbon/epoxy laminates.
