Struktursimulation Endlosfaserverbunde
The deformation and damage behavior of continuous-fiber composite components is largely determined by the structure of the reinforcing fibers. Fiber orientation, fiber volume content, and local effects such as waviness and gapping can vary significantly as a result of the forming process. To consider this in the prediction of the structural mechanical behavior, we incorporate the process information provided by the CAE chain in the structural simulation. For this purpose, we develop material models that capture the nonlinear deformation behavior and the damage evolution in a failure mode-specific manner (fiber fracture, matrix fracture, delamination) as a function of the local fiber structure.
