Abstract: The effect of density, cell size, molding method and surface roughening treatment (foam, panel) on the peel strength of PMI foam sandwich structure composites were systematically investigated. The results showed that foam density, cell size, molding method and surface roughening treatment can efficiently improve the peel strength. And, the most significant is the foam density and cell size, which improve 157% and 95%, respectively. This study provides excellent technical guidance for the improvement of peel strength for PMI foam sandwich structure composites.

Key words: PMI foam, sandwich structure, peel strength
