Study of the residual stresses in a thermoplastic filament winding process for high-pressure H2-storage vessels.

The target is to obtain a series of FEA-models that are capable of predicting the mechanical performance (burst-pressure) of thermoplastic composite high-pressure vessels for H2-storage applications. The project will start with an accurate characterization of both process and materials. Secondly, a thermal model and a process-model will be built that are able to predict the residual stress state and microstructure after winding. This result will serve as an input for a burst-pressure model, used for predicting the burst-performance of the vessel. All models will be created using efficient simulation tools and updating algorithms. Lastly, they will be validated using state-of-the-art methods and technology.
