Abstract
A new hybride aluminium polymer foam was developed in order to combine the good energy absorption capability of aluminium foams with the easy applicability of polymer foams. Technological approach was to coat aluminium foam granules with polymer adhesive which foams up during the thermally activated curing. In the presented work the influence of the polymer and aluminium content upon the compression behaviour of hybride foams produced under realistic situations were systematically investigated. Linear regression analysis of several characteristic values of the compression stress-strain curves demonstrated a dominating influence of the polymer. Reasons for this can be combined effects of polymer mass increase and structural changes of the overall hybride foam. Generally, hybride foams seem to have some advantages in comparison to simply bonded structures of aluminium foam granules. Future investigations have to be directed to foams with higher densities and to the compression behaviour at higher deformation rates.
