Abstract Scope |
Hybrid aluminium means the group of aluminium matrix composites, aluminium foams, and sandwich structures with aluminium foam core. Closed cell aluminium foams are invented nearly 100 years ago. They are mainly targeted as structural materials. There are three main technologies: blowing agent mixing into foamable melt, powder compaction foaming, foaming with gas injection which are used to produce closed cell aluminium foams. Besides the light weight of the closed cell aluminium foams there are three main properties as aesthetics, specific stiffness and mechanical energy absorption which are driving three industrial customer groups: Design and building industry – key property is aesthetic. Defence and safety industry – key property is mechanical energy absorption Mobility and machinery – key property is specific stiffness. Based on public information the recent producers, the main products, the largest projects and market possibilities will be summarised. |
