Abstract

A special challenge for the polyurethane sandwich manufacturing process is that the material properties strongly depend on the manufacturing process. This has to be considered in the design of such sandwich structures. As part of the work presented, the basic material parameters were determined from sandwich structures produced using the polyurethane fibre spraying process. Furthermore, the critical failure modes were determined using 3- nd 4-point-bending tests. These results can be used to design and simulate such sandwich components with FEM.
