Grid-Stiffened composite structures have found their way into a variety of apphcations for their structural efficiency, cost and inherent damage tolerance. Where previous studies and research have focused on global optimization of the far-field grid structure, the current work focuses on the development of an efficient though versatile load introduction zone at the edge of the structure. A global lightweight design requires structural efficiency throughout the structure. Therefore, having a versatile design for the load introduction zones allows for optimization of the far-field structure and can result in a design that efficiently transfers loads to the next structure. To this end a design is developed where the ribs are interwoven with a laminate which can then easily be connected to the next structure. A parametrized Finite Element Method model has been verified through correlation with two different designs which also proves versatility of the rib-to-laminate concept. Using this FEM model the load introduction zone can be optimized for a variety of grid structures and layouts. Since limitations and effects of the manufacturing process can make or break a design, the two analyzed designs are manufactured and tested to prove feasibility and performance. Their quality is assessed and used as input for improvement of the FEM model. The end result is a parametrized and verified concept for load introductions that can be used in the giobfil optinrization of a grid-stiftened composite structure.
