A methodology is proposed for predicting the formation and the development of the manufacturing
residual stresses, this approach is based on the study of the evolution of the resin yield stress. In order to
evaluate our method, a comparison has been made between the yield time (corresponding to the formation of
a yield stress) and the gel time. A self-consistent model is used to determine the cure-dependent chemical
shrinkage coefficient of the composite material. This model allows considering for the composite material
behavior an anisotropic chemical shrinkage, which is not represented by a classical linear model. An
experimental approach based on the peel-ply method is used to determine the distribution of the residual
stresses through the thickness.
Key words: Epoxyresin composites, manufacturing process, peel-ply method, residual stresses, thermal and mechanical characterizations, ,
