Validation of composites forming simulations is essential to improve simulation predictions. Detailed validation requires reliable and well-controlled forming processes with precise methods for comparison to simulation results. This study presents some preliminary results from press forming experiments with cross-ply laminates shaped over a dome geometry. The material studied is a unidirectional carbon-fiber reinforced thermoplastic composite. The forming experiments were combined with a deformation measurement technique based on photogrammetry to measure the in-plane deformation on the surface of the laminate after forming. The obtained full-field deformation measurements allow for a direct and quantitative comparison with simulations. The accuracy and precision of the methodology are discussed in detail. The combination of a versatile forming experiment and a detailed analysis method as presented in this article could enable a more precise validation of composite forming simulations.
