The filling process of moulds is simulated, which are carrying fibre and textile reinforcements for the produced components. Methods to model non-Newtonian fluid flow through fibre beds. A two-phase continuum constitutive model has been developed and FE-implemented for simulation of the HTex process, which involves simultaneous impregnation and forming A new method to determine thermal contact conductance between metal tooling and composite has been developed. Using the method a set of thermal contact conductance data has been generated. The thermal contact conductance is of importance both for JETex and HTex process simulations. A thermo-chemo-mechanical process model has been developed for the JETex process and implemented in the FE-program ANSYS. The model includes both thermal and mechanical part-tool interaction.
