Fast moved machine tool assemblies should be light and stiff. By reason of the lightweight construction and the dynamical loads these assemblies are susceptible to vibrations very often.
Aluminium foam sandwiches are laminates with an aluminium foam core and compact cover sheets. The foam cores have an high energy absorption. Machine tool assemblies constructed with aluminium foam sandwiches have a very high bending stiffness by a comparatively low weight. Vibrations generated by machining are damped very well due to the cellular structure of foam.
Manufacturing of foam sandwiches is understood. Questions are mechanism of bonding and adhesion between cover sheets and foam core. Answers of theses themes are given in this script.
