Abstract
Advanced pore morphology (APM) foam, consisting of sphere-like metallic foam elements, proves to have advantageous mechanical properties and unique application adjustability. Since the APM foam manufacturing procedure has been developed recently, the mechanical characterization of these materials is still very limited. Therefore, the purpose of this research was to determine the behaviour of APM spheres and its composites when subjected to quasi-static and dynamic compressive loading. The results of the performed research have shown valuable mechanical properties of the composite APM foam structures, offering new possibilities for their use in general engineering applications.
Highlights
Development, design, manufacturing, characterisation and application of conventional cellular structures used in composite materials have been widely studied and reviewed [1,2,3,4]
A new type of cellular materials has been developed, the Advanced Pore Morphology (APM) foam, which consists of sphere-like metallic foam elements, characterised by advantageous mechanical properties and unique applicability
The APM foam has a wide potential application spectrum as energy absorbing structure, stiffening elements, core layers, damping elements or bonded with a matrix in composite materials. One of their main advantages is their simple use as filler elements increasing the energy absorption of hollow parts, e.g. a hollow automotive part can be filled with APM foam elements covered with adhesive, the filled part is heated up to join the APM foam elements
Summary
Development, design, manufacturing, characterisation and application of conventional cellular structures used in composite materials have been widely studied and reviewed [1,2,3,4]. A new type of cellular materials has been developed, the Advanced Pore Morphology (APM) foam, which consists of sphere-like metallic foam elements, characterised by advantageous mechanical properties and unique applicability. Since the APM foam manufacturing procedure has recently been developed, the mechanical characterization of these materials is very limited. The purpose of this research was to determine the behaviour of the APM foam elements subjected to compressive loading. Single APM foam elements were experimentally subjected to quasi-static and dynamic compressive loading, providing the basic properties and knowledge for an efficient application of composite APM foam structures
