Tolerance management during the design of composite structures considering variations in design parameters

Abstract Composite structures play an important role in realising resource-efficient products. Their high lightweight potential and improved manufacturing technologies lead to increased use high-volume However, especially during the design development of products, consideration uncertainties is essential guarantee final product quality. In this context, modern materials, such as fibre reinforced plastics (FRP), leads new challenges. This due their number parameters, which are subject deviations from nominal values. Deviating e.g. ply angles thicknesses, influence process well structural behaviour a composite part. To consider deviating parameters process, tolerance optimisation approach presented, defining values for laminate while ensuring functionality structure. reduce computational effort, metamodels used replace finite element simulations. The proposed applied case with different key functions show its applicability benefits.
