چکیده
A 3D interpenetrating phase composite (IPC) foammade by infusing syntactic foam (SF) into an open-cell aluminum scaffold is studied under high-strain rate conditions. The SF is prepared by dispersing hollow glass microballoons into an epoxy matrix. Dynamic compression characteristics, including strength and failure progression of pure SF and IPC foammade of four different volume fractions ofmicroballoons in SF measured using a split Hopkinson pressure bar (SHPB) apparatus are reported. The results show that in

Quasi-static and dynamic compression response of a lightweight interpenetrating phase composite foam
Quasi-static and dynamic compression response of syntactic foam (SF)–aluminum foam interpenetrating phase composites (IPC) is examined. Infusion of uncured syntactic foam (epoxy filled with hollow microballoons) into an open-cell aluminum network results in a 3D interpenetrating structure upon curing. The compression responses are measured at strain rates of ∼0.001/s and 1500/s. The dynamic exp...
متن کاملExperimental and Numerical Simulation Investigation on Crushing Response of Foam-Filled Conical Tubes Stiffened with Annular Rings
In this paper, crashworthiness characteristics of conical steel tubes stiffened by annular rings and rigid polyurethane foam are investigated. For this purpose, wide circumferential rings are created from the outer surface of the conical tube at some determined areas along tube length. In fact, this method divides a long conical tube into several tubes of shorter length. When this structure is ...
متن کاملEffect of Fe additive on plastic deformation for crush-boxes with closed-cell metal foams, Part I: Al-composite foam compression response
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...
متن کاملThe Effect of Fe Additive on Plastic Deformation for Crush-Boxes with Closed-Cell Metal Foams, Part II: Al-Composite Foam-Filled brass tubes Compression Response
The brass tubes with foam cores of AlSi7SiC3, AlSi7SiC3Fe1 and AlSi7SiC3Fe3 were produced as the crush-boxes with circle and square cross-section. Then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. The uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...
متن کاملImproving the Performance of the Sandwich Panel with the Corrugated Core Filled with Metal Foam: Mathematical and Numerical Methods
A new type of composite structure with a metal foam is reinforced by the metal corrugated core, called metal-foam-filled sandwich panel with a corrugated or V-frame core, is modelled, simulated, and studied in this article. All types of samples with different relative densities of the foam are tested and analyzed under the drop hammer load. The sandwich panel included two aluminium face-sheet, ...
