Résumé

Autoclave curing of composite parts involves multiphysical mechanisms causing residual deformation. Respecting the geometric tolerances of the part can constitute a real challenge, and requires the design of a compensated mold. The objective of this study carried out on composite plates is to develop a digital mold design method. For this, a tool for predicting residual deformations was developed. This is coupled with a method for calculating the shape of the compensated mold. This method is applied on a thick plate and on the thin fabricated plate in order to study the convergence of the optimization problem in both cases. The correction method thus studied works well on thick plates, but works less well on thin plates because of non-linearities.
