Abstract: |
This paper presents results of analytical, experimental and numerical investigations on the mechanical behaviour of sandwich panels with glass fiber reinforced polymer (GFRP) skins. The performance of two different core materials - rigid plastic polyurethane (PU) foam and polypropylene (PP) honeycomb - and the effect of using lateral GFRP ribs along the longitudinal edges of the panels were investigated. The experimental campaign first included material characterisation tests on small scale specimens. Subsequently, flexural static and dynamic tests were carried out in full-scale sandwich panels in order to evaluate their service and failure behaviour. The numerical study included the development of 3D FE models of the tested sandwich panels, which allowed simulating the mechanical behaviour of the sandwich panels with a good accuracy. |
