Aluminum foam is usually used as the core of composite materials by combining it with dense materials, such as in Al foam core sandwich panels and Al-foam-filled tubes, owing to its low tensile and bending strengths. In this study, all-Al foam-filled tubes consisting of ADC12 Al-Si-Cu die-cast aluminum alloy foam and a dense A1050 commercially pure Al tube with metal bonding were fabricated by ...
The favorable energy-absorption properties of metal foams have been frequently proposed for damping or anti-crash applications. The aim of this paper is to investigate the endurance of these properties for composite structures, made by a metal or a hybrid metal-polymeric foam used as the core filling of a tubular metal case. The results of experimental tests are shown, run with two types of str...
Due to their lightweight, porous and excellent energy absorption characteristics, foam honeycomb materials have been widely used for filling absorbing devices. For further improving the performance of novel tube proposed in our recent work, nonlinear dynamics software Abaqus was firstly establish verify simulation model aluminum-filled tube. Then, crashworthiness honeycomb-filled tubes, foam-fi...
The main objective of this research is to manufacture expanded perlite (EP) foam-filled stainless steel tubes for energy absorption application and investigate their physical compressive behavior. Foam-filled (FFT) were manufactured by consolidating perlite/sodium silicate composite foam inside the tube. EP particles size 5-6 mm taken manufacturing FFTs. Two different sodium solution water (S/W...
-The characteristics of a number of metal components proposed as impact energy absorbers are reviewed, attention being focussed on to modes of deformation which stem from the axial compression of metal tubes. Progressive buckling, inversion and splitting are discussed and areas for future work identified. The buckling of thin-walled square section tubes filled with polyurethane foam is also des...
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...
In this paper, the behavior of energy absorption of crush-boxes, made of Aluminum foam advanced material, was investigated based on foam cellular structure homogeneity. Therefore, thin-walled tubes of Cu-Zn30wt.%.brass alloy with 27 mm diameter and 1 mm thickness were filled with A356-10vol.%SiC-Xwt.%. of TiH2 foam liquid. Foam samples with 1, 1.5, 2wt.%. of TiH2 were prepared by Form Grip into...
abstractin this paper, we investigate effect of fe–intermetallic compounds on plastic deformation of closed-cell composite aluminum foam as filler of thin-walled tubes. however, deformation of the aluminum foam-filled thin-walled tubes as crushed-box will be presented in part (ii). composite foams of alsi7sic3 and alsi7sic3-(fe) as closed cell were synthesized by powder metallurgy foaming metho...
