Abstract
Thermoplastics are favourable to the automotive industry due to their recycling possibility. Carbon fiber reinforced thermoplastics (CFRTP) are passed through the automotive paint shop. The imposed thermal loading presents a challenge to implementing economically feasible CFRTP in body structures. The present study provides a simulation approach to analyse the anisotropic viscoelastic deformation behaviour to assess this scenario. Validation experiments were conducted by optically measuring the out-of-plane displacement of dry and moisture-saturated specimens subjected to a simulated cathodic dip painting-dryer. Preliminary lay-up assessment for the automotive painting process is deemed possible due to the good agreement between simulation and experiments.
