Abstract

This paper presents the results of static and dynamic crushing of wood sandwich tubes made with a birch core and carbon woven skins. 3 tubes (external diameter 64 mm, length 120 mm) were crushed in static and 3 others in dynamic under a drop tower. The results reveal very interesting energy absorption performance of such structures. The Specific Energy Absorption is 50.4 J/g in static and 66.6 J/g in dynamic, the energy absorbed is 5427 J in static and 7045 J in dynamic (170 kg launched at 4.2 m). These characteristics, which are quite comparable with those of tubes made of composite materials or aluminum alloys, show that these sandwiches with birch core are serious candidates for energy absorption with renewable materials.
