Sandwich structures represent a lightweight design method which leads to very light and at the same time stiff components through the combination of stiff outer skins and light core material. A major challenge in the design of sandwich structures is load introduction. In order to realize improved load introduction in sandwich structures and to leverage further possible lightweight design potential, the following paper presents a new concept using spider web inspired structures made of fiber reinforced plastic materials. In order to investigate the potential of the spider web concept, simulative comparative studies between the spider web structures and conventional load introductions are carried out.
