Abstract
The compressive capacity of composite foam sandwich tube is influenced by the fabrication process. Foam sandwich composite tube is made with technology of filled foam precut and curing molding together with prepreg ply. In order to clarify the interface to the bearing capacity, dynamics finite element software LS-DYNA was used to simulate the model whose interface is polished and waxed or not. The delamination was observed by the deformation cloud picture and displacement difference curve. The simulation showed that the composite foam sandwich tube which interface was polished and waxed before it was formed has relatively higher carrying capacity than that none-polished and none-waxed.
