Filtration is the most cost effective method to purify aluminum. In this paper, filtration experiments have been carried out using both AlF3 slurry coated, and uncoated Al2O3 ceramic foam filter (CFF) to study the removal of both nonmetallic inclusions and impurity elements. The results showed that the 30 ppi CFF removed up to 85% inclusions from aluminum. The contributing mechanisms for the re...

Developing biofoams constitutes a challenging issue for several applications. The present study focuses on the development of a chitosan-based biofoam. Solutions of chitosan in acetic acid were dried under vacuum to generate foams with high-order structures. Chitosan concentration influenced significantly the morphology of developed porosity and the organization of pores in the material. Physic...

Application of foam in EOR, increases macroscopic sweep efficiency via awesome increscent of mobility control. Macroscopic manifestation of foam application performance in porous media is complex process that involves several interacting microscopic foam events. Stability as an important factor in foam injection within large reservoirs, depends on several variables including oil saturation, con...

aluminum foams are a novel branch of advanced materials with superior properties. sandwich structures with aluminum foam core are good energy absorbers. in this paper, mechanical properties and energy absorption of aluminum foam sandwich panels subjected to quasi-static perforation tests with conical-nosed indenter were investigated experimentally. for this purpose sandwich panels consisting of...

Sandwich panels are systems with structural functions that used in the field of civil construction, currently, they construction buildings and also as cladding for walls, ceilings, among others. This article shows results an experimental comparative analysis behavior fire resistance two sandwich function composed Polyisocyanurate (PIR) foam core fiberglass-reinforced fabric dimensions 3150 mm ×...

Porous polymer-derived ceramics (PDCs) are outperforming materials when low-density and thermal inertia required. In this frame, insulating foams such as silicon carbide (SiC) ones possess intriguing requisites for aerospace applications, but their conductivity is affected by gas phase heat transfer and, in the high temperature region, radiative mechanisms. Owing to versatility of PDC route, we...

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...
