Inverse Characterization Method For Draping Simulation Based On Automatic Measurement Of Fiber Orientation

FibreMap project aims at the development of an automatic quality control and feedback mechanism to improve draping of carbon fibers on complex parts. There is a strong need in the automotive industry for automatic systems that perform quality control and improve draping processes in order to allow high production volumes. From the simulation point of view, the FibreMap projects aims to develop inverse method allowing material characterization from measured fiber orientation. Indeed, material parameters are key inputs for draping simulation software but they are dicult and somehow expensive to identify. This situation can lead to poor quality of simulation results due to bad material parameters. FibreMap project proposes to overtake this issue by developing a unique optimization loop. Simulation results are compared to experiment results through projection of measured fiber orientation on the finite element mesh. Then PAM-OPT capabilities and comparison tool developed by INSA-Lyon are used to modify the simulation input (material parameters) in order to improve simulation results accuracy. Finally, the convergence of simulation results towards measured fiber orientation leads to a better knowledge of the material to be draped.
