Abstract
[en] The manufacturing process of thermoset composite materials is done at high temperature to allow the polymerization of the resin, and a temperature cycle is therefore defined. When RTM (Resin Transfer Molding) is concerned, dry fibers are placed in a mold and the resin is injected at high temperature. Thermal and chemical strains appear during the process, and the produced part naturally presents a shape distortion. Residual stresses also appear, with some relaxation over time. Thermo-chemicomechanical finite element analyses can be conducted to predict the shape distortion. Thermal and chemical models exist, and their parameters must be identified. Also, the boundary conditions (e.g. contact and friction with the mold) can influence the distortion and residual stresses. In this work, the student will study with the FEM approach these different effects on the resulting geometry and residual stresses distribution
