Compression molding (SMC/LFT)

The simulation of the compression molding process of discontinuous reinforced polymer aims at describing the mold filling of a moving mold cavity.  We focus on the manufacturing process of long fiber reinforced thermoplastics (LFT) and sheet molding compound (SMC). In these simulations, the flow process is considered taking into account process parameters and material properties. As a result, the filling state, fiber orientation and process forces are predicted.


Research focus
  • Modeling anisotropic flow
  • Direct Bundle Simulation for a precise prediction of the fiber architecture
  • Direct simulation of fiber suspensions for parameterisation of macroscopic fiber suspensions
  • Process optimization
  • Warpage simulation
