Abstract: Abstract This study presents static compression of sandwich tubes for crash applications in the transportation industry. The tubes were made from “I214” poplar veneers for the core, and carbon or glass woven plies reinforced with epoxy resin composites for the skins. The number of I214 layers in the core was varied between 2 and 6 while keeping the same number of plies for the skins. The results reveal interesting energy absorption performance of such structures in static, together with a coupling effect. In comparison with reference, all-c...
