Epoxy aluminium hybrid foam - An innovative sandwich core material with improved energy absorption characteristics
Abstract
Solid foams are important core materials for sandwich structures. One of their main advantages is their ability to perform in multi-functional applications combining the structural function of a sandwich core under regular service conditions with other functions. Especially the energy absorption capability under accidental crash or impact conditions has to be mentioned. Solid foams can be pro-cessed from different base materials with different advantages. Whereas polymeric foams are extremely lightweight materials, their energy absorption capability is limited. Here, metallic foams have advantageous properties, however, at a larger specific weight.
