• Properties of metal foams are sensitive to not only porosity but also topology. Thermal conductivities commercial stochastic almost isotropic. Architected have 103% higher thermal conductivity than foams. stiffer and absorb 265% more energy This study conducted pore-scale simulations estimate the stagnant mechanical performance architected The 5-, 10-, 20- 40-ppi aluminum were estimated be 6....

This work presents the preparation and characterization of compression-moulded montmorillonite and carbon nanofibrepolypropylene foams. The influence of these nanofillers on the foaming behaviour was analyzed in terms of the foaming parameters and final cellular structure and morphology of the foams. Both nanofillers induced the formation of a more isometric-like cellular structure in the foams...

Due to the manifold properties of porous materials in general, and metal foams particular, they are increasingly used industrial, structural functional applications. The depend on: chemical composition, metallurgical aspects, processing morphology (the type porosity: open or closed), amount porosity, cells size shape. There challenges difficulties encountered welding bonding from wider use prod...

Metal foams constitute a promising and emerging material class in the context of lightweight construction. There exists variety different foam topologies, on which resulting mechanical properties depend. To maximize potential use under load, present work addresses question how geometrical parameters influence behaviour. Therefore, an algorithm for digital generation design open pore structures ...

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...

Metallic foams with pore sizes from 250 lm to 2 mm have been a subject of research for over two decades due to their high surface area, which allows for a variety of applications, such as thermal and sound insulation. Recently, processing of metallic foams at the nanoscale (pores sizes less than 100 nm) has opened the door to new and interesting applications, such as sensors and actuators. In g...

BACKGROUND Foams are high porosity and low density materials. In nature, they are a common architecture. Some of their relevant technological applications include heat and sound insulation, lightweight materials, and tissue engineering scaffolds. Foams derived from natural polymers are particularly attractive for tissue culture due to their biodegradability and bio-compatibility. Here, the foam...

Sulfur (S) cross-linking styrene butadiene rubber (SBR) foams show high shrinkage due to the cure reversion, leading to reduced yield and increased processing cost. In this paper, double cross-linking system by S and dicumyl peroxide (DCP) was used to decrease the shrinkage of SBR foams. Most importantly, the synergy of double cross-linking agents was reported for the first time to our knowledg...

Al foam has been used in a wide range of applications owing to its light weight, high energy absorption and high sound insulation. One of the promising processes for fabricating Al foam involves the use of a foamable precursor. In this study, ADC12 Al foams with porosities of 67%-78% were fabricated from Al alloy die castings without using a blowing agent by the friction stir processing route. ...
