APM aluminium-polymer foams and derived materials: A survey on properties, applications and development trendsThursday (09.11.2017) 10:35 - 10:55 Part of:
“APM-foams” have been derived from classic “Foaminal” or powder compact melting metal foaming technology in order to facilitate the integration of foams into hollow structures like tubes, extruded profiles or welded components. The main advantage of the technology is the significantly reduced thermal load exerted on the structure to be filled. Besides, the particulate nature of the foam prior to consolidation allows filling of structures with complex geometries including re-entrant angles and undercuts. The initial technological approach was to merge a multitude of aluminium foam granules with help of hot curing adhesives to larger foam structures. Using expanding hot-curing polymers the approach was quickly extended to the production of so-called hybrid aluminium-polymer foams. Recent developments include the use of cold-curing polymer foams and organosilicon heat resistant binders. In the presentation, the basic principles of the production technology, including the aforementioned special variants, will be described and the fundamental properties of the different foam types summarized and contrasted to each other as well as other types of metal foams. Recent application and prototype studies and current developments will be presented.
