title = "VALIDATING SIMULATED RESIDUAL STRAINS DUE TO THERMOFORMING USING FBGS",
abstract = "Accurately determining process induced residual strains in carbon fiber reinforced plastic (CFRP) and CFRP-metal hybrids is vital for understanding the behavior of manufactured components and to validate simulations of process induced deformations. The required local strain measurements for this task can be obtained with Fiber Bragg Gratings (FBGs), embedded between CFRP layers. The required strain and temperature calibrations is carried out in a tensile testing machine. FBGs were used to monitor the manufacturing process of CFRP and hybrid plates in a thermoforming station until demolding. Good agreement in terms of strain results and visibility of major effects such as crystallization behavior between measurement data and process simulation results has been achieved.",
