• Foldcore
• Aramid fibre
• Finite element analysis (FEA)
• Mechanical testing

Foldcore is an origami-like structural sandwich core which is manufactured by folding a planar base material into a three-dimensional structure. The manufacturing technology is open to a variety of base materials and also a range of unit cell geometries is feasible. FE-simulation is used to support mechanical testing of foldcores. Required input data for FE-simulation is a material model of the base material. So a test programme for aramid paper, the actual standard base material for foldcore production, is developed. A material model is extracted from test data and implemented in commercial FE-codes.
