摘要：
The article presents the results of dynamic crushing of sandwich tubes that had skins made of carbon or glass fibers - with epoxy resin - and an I214 poplar ply core. By increasing the number of poplar plies from two to six, the absorbed energy is doubled, showing the significant contribution of the wood. The Specific Energy Absorption of sandwiches with carbon fiber skins oscillated between 49.4 J/g and 60 J/g while that with glass fiber skins varied from 35.4 to 43.3 J/g.
