| Abstract Scope |
Manufacturing of metal/polymer sandwich composites via roll bonding can offer great advantages over other techniques such as overmolding, which are more complex and costly. Roll bonding of multilayer composites, however, is challenging due to the large difference in mechanical properties and adhesion characteristics of polymeric and metallic materials. In this study, warm roll bonding (WRB) has been applied to fabricate sandwich composite consisting of commercially aluminum (Al1100) and polyurethane (PU) sheets. The effects of WRB process parameters, which include surface roughness, preheat temperature, and rolling speed, on the adhesion strength have been investigated by the peel test. The optimal temperature and rolling speed were identified for WRB of Al1100/PU/Al1100 sandwich composite. Furthermore, 3-D finite element analysis has been adapted to simulate the failure stages of metal/polymer sandwich composite under either static or cyclic peeling load. Virtual-Crack-Closing-Technique (VCCT) debonding model has been employed to predicate such stages of peeling failure. |
