This study aims to develop a novel technique in manufacturing nanocomposite bimodal foams containing expandable polymeric microballoons. Low density polyethylene syntactic were prepared via injection molding process, afterwards, batch refoaming method was utilized create structure. The effects of microballoon and nanoclay content foaming time temperature on microstructure physical properties in...

Auxetic (negative Poisson's ratio) open cell polymeric foams have been traditionally produced using thermoforming techniques coupled with the volumetric compression of conventional (pristine) off-the-shelf foams. The anisotropy pristine foam plays however a strong role on performance thermoformed auxetic foams, and this is subject studied in work. Micro computed tomography (μ-CT) scans indeed s...

In this study, at first Al-Al2O3 composite powders having different volume fractions of Al2O3 (0, 10, 20, 30 and 40 vol.%) were produced by low energy mechanical alloying, which were used as foam materials. Then, composite foams with 50, 60, and 70 percent of porosity were produced by space-holder technique. Spherical carbamide particles (1-1.4 mm) were used to achieve spherical porosities. In ...
