Composite materials fabricated using hollow microspheres are called syntactic foams. Particulate filler composites such as syntactic foams, consisting of glass microballoons and epoxy resin, are desirable for applications that require high compressive and impact strengths and low thermal conductivities. However, for heat dissipation applications, filler additions are required to increase the th...

Abstract Aluminum foam sandwich (AFS) is an innovative material combination for designing lighter products and has many advantages such as a high bending stiffness at low density good energy absorption properties. Although the ready series production, number of industrial applications because costs material, lack design knowledge missing reference applications. This paper focuses on aspect how ...

A layered gradient aluminum foam was prepared by powder sintering with sodium thiosulfate (Na2S2O3) particles as the cell-forming agent. By cutting, polishing and observing under a microscope, it found that were not completely melted after but only combined surface melting. Based on quasi-static compression test macroscopic diagram of sample during deformation, mechanical properties studied, th...

1. Introduction In recent years there has been an increasing number of applications requiring more efficient and lightweight thermal management such as high-density electronics, hybrid diesel-electric vehicles, communication satellites, and advanced aircraft. The primary concerns in these thermal management applications are high thermal conductivity, low weight, low coefficient of thermal expan...

foam injection is becoming a standard conditioning agent when tunnelling with an earth-pressure balanced shield, resulting in an increasing interest in this technique. the technique is mostly based on empirical rules and experience. to be able to determine what foam and how may foam has to be injected for different soils, it is necessary to know the mechanical parameters of the foam-water-soil ...
