The microstructure and mechanical properties of open-cell metal foams have long been studied from various angles. The materials discussed in this paper were fabricated using an unconventional sintering method and their properties are unique. An important part of the process is reduction of Fe(III) oxide, acting as a foaming agent and a space holder. Four powder mixtures were analysed: ASC100.29, ASC100.29 + C, DISTALOY SE and DISTALOY SE + C. The aim of the tests, performed with a specially developed setup, was to determine the impact energy absorption capacity of the Fe-based foams. From the results, it is clear that the metal foams can be used in many applications, including lightweight structures, filters, heat exchangers and energy-absorbing systems. Keywords: open-cell metal foams, Fe-based foams, reduction of metal oxides, space holder technique, energy dissipation Highlights • The Fe-based metal foams were produced through sintering, which is an efficient and cost-effective process. • The reduction of Fe (III) oxide by hydrogen and the addition of Cu were responsible for a uniform structure and open porosity. The average pore diameter did not exceed 100 µm; the porosity ranged from 67.9 % to 80.3 %, depending on the powder mixture composition. • The motion of the hammer striking the material was monitored using a time-lapse camera. • The Fe-based foams seem suitable for lightweight structures, energy-dissipating and energy-absorbing systems, filters, catalytic converters, and heat exchangers.

“…When worn in the mode of structural and energy adaptation of the friction surface, the sub-relief of the friction surfaces is covered by secondary structures of its type and is caused mainly by the presence of smoothed areas. The sub-micro-roughness of the patches is negligible [31][32][33][34].…”

The original test results of abrasive wear resistance of different type of construction polymer materials were presented and discussed in this article. Tests were made on an adapted test stand (surface grinder for form and finish grinding). Test samples were made of different types of polymer board materials including RenShape®, Cibatool® and phenolic cotton laminated plastic laminate (TCF). An original methodology based on a grinding experimental set-up of abrasion wear resistance of polymer construction materials was presented. Equations describing relations between material type and wear resistance were presented and discussed. Micro and macro structures were investigated and used in wear resistance prediction.

“…18,21,31,32 However, metallic hollow spheres developed in recent years are a relative controllable cavity material with size and distribution, which can solve the above shortcomings of PU foam. In recent years, metallic hollow spheres have been widely reported in the field of metal foams, [33][34][35][36][37][38] while there are few reports about hollow metal spheres/polymer composites. Yu et al 39 has previously studied the effect of different polymer molecular structures on the acoustic properties of metallic hollow spheres/polymer composites.…”

In this article, 316L stainless steel hollow spheres (316L HS) and polyurethane (PU) resins were used to prepare a novel metallic-hollow-sphere/polyurethane (MHSP) acoustic composite by casting. The acoustic experimental results of this composite revealed that compared to monolithic PU, the sound transmission loss of the composites increased and the maximum sound absorption peak shifted to lower frequency with the change of acoustic impedance and resonance frequency. When the surface of metallic hollow sphere used in MHSP composite was modified by silane coupling agent, the sound insulation and sound absorption performance of MHSP composites were further improved. This is related to the addition of the molecular layer of coupling agent between MHSP matrix. In addition, the addition of silane coupling agent creates PU foaming in matrix, resulting in a large number of pores and gaps that can increase the sound waves energy loss through air friction and heat exchange.
