Abstract
The characteristics of two new structures, namely (1) origami tube structure and (2) truss core panel are checked as a measure to protect pedestrians. Origami tube structure shows an alternative procedure of changing the origami structure to give it robustness of characteristics against the impact angle. Truss core panel is a rigid panel developed from the geometry on space filling. Honeycomb has a similar high stiffness performance. This is produced by adhesion or brazing, so it's weak against heat and very expensive. On the other hand, truss core panel can be made with metal and be welded, so it's strong against heat and usually cheap, which showed outstanding strength characteristics.
