Abstract Composite metal foams are hybrid structures with the main advantages of high specific strength and mechanical energy absorption associated low density. In course our research, we successfully manufactured functional EN AC-44200 matrix filled lightweight expanded clay aggregate particles (LECAPs) in AW-6060 alloy tubes a diameter 50 mm wall thickness 5 mm. Manufacturing was performed by...

The work focuses on research related to determination of application possibility of new, ecofriendly boroorganic polyols in rigid polyurethane foams production. Polyols were obtained from hydroxypropyl urea derivatives esterified with boric acid and propylene carbonate. The influence of esterification type on properties of polyols and next on polyurethane foams properties was determined. Nitrog...

Electrochemical behaviour of 4.8 ± 0.2 nm graphene films on nickel and copper foams was investigated by cyclic voltammetry (CV). The were prepared chemical vapor deposition characterized electron energy loss spectroscopy, elastic peak scanning microscopy X-ray photoelectron spectroscopy. CV the [Ru(NH3)6]+2/+3 redox reaction performed using these substrates. obtained results demonstrated a high...

Abstract This paper is dealing with the production and investigation (structural mechanical) of composite metal foams (CMFs) AlSi9MgMn matrix ~60 vol% different nominal diameter light expanded clay particles (LECPs) filler. The main aim was to produce a cheap CMF grade for automotive industry. samples were produced by liquid state low pressure infiltration. Cubic manufactured from blocks struct...

Highly uniform samples of carbon nanofoam from hydrothermal sucrose carbonization were studied by helium ion microscopy (HIM), X-ray photoelectron spectroscopy (XPS), and Raman spectroscopy. Foams with different densities were produced by changing the process temperature in the autoclave reactor. This work illustrates how the geometrical structure, electron core levels, and the vibrational sign...

The present work investigates the compressive property of Al matrix composite foams at different temperatures between room temperature and 200 ◦C. Elevated temperature results in a decreased compressive strength and energy absorption capacity of as-received Al foams. Therefore, to maintain the compressive property, the Al2O3 ceramic coating was deposited on the Al struts of the foams by the pla...

Compressive behaviour of bovine cancellous bone and three open-cell metallic foams (AlSi7Mg (30 ppi and 45 ppi); CuSn12Ni2 (30 ppi)) has been studied using mechanical testing, micro-focus computed tomography and finite element modelling. Whilst the morphological parameters of the foams and the bone appear to be similar, the mechanical properties vary significantly between the foams and the bone...
