Predicting the Influence of Manufacturing Parameters on Curing Generated Deformations Using Thermo-Mechanical Modelling

Abstract


The present study is related to the prediction of residual stresses and associated cure-induced distortions that commonly occur during the manufacturing of fiberreinforced thermosets. RTM-6 is used as the matrix material, as abundant literature data is available for both the cure kinetics and the mechanical response as function of different cure degrees. After the final shape has been virtually demolded from the component, it is compared to the as-designed shape, i.e. the surface of the mold. This allows to numerically investigate the effect that changing manufacturing and design parameters, such as applied thermal profile, lay-up, part thickness and shape, can have on the cure-induced deformations. To this end, the simulations will be compared to experiments performed from the literature using C- and L- shaped parts.
