Progress in Research and Application of Aluminum Foam Sandwich Panels

Aluminum foam sandwich (AFS) panel is an advanced material-structure integral cellular composite structure based on Al foam. AFS panel has extensive applications in transportation, architectural and aerospace industry, which is looked forward to reduce the structures weight of devices. Principle and current status of the producing techniques are overviewed, based on which, particularly, several scientific and technical obstacles on the fabrication of composite precursor, designing of alloy constituent, in-situ foaming process etc. are discussed. Then, some representative applications of AFS as both structural and functional materials are introduced. In the end, both the challenges and keynotes on materials investigation and technique developments are proposed.
