Forming pressure of PMI foam sandwich structure

Abstract

In this study, the performance of A-reinforced sandwich structures made with polymethacrylimide (PMI) foam material is explored. The research focuses on comparing two forming methods, bonding and co-curing. It also tests the static properties of sandwich test pieces under different forming pressures. It reveals that the foam sandwich structure formed under the 0.15 MPa bonding process outperforms the rest regarding static properties. These findings provide valuable insights into the optimal structure-forming process for PMI foam sandwiches, paving the way for future advancements in this field.
