The basic manufacturing processes of cellular materials have been briefly noted as well as the metal foam properties. The most widely used are the aluminium foams due to the following properties: very good insulation (thermal insulation and sound absorption), low density (mass), high specific rigidity in sandwich structures, very good impact damping, corrosion resistance, non-flammability, very...

This paper describes an accelerated ageing experiment of transformer oil/paper insulation with preset moisture levels. These samples were tested with return voltage and polarisation/depolarisation measurements. Molecular weight has also been measured with Gel Permeation Chromatography (GPC). Results suggested the impact of moisture on the ageing of oil/paper insulation. An attempt has been made...

Recycling treatment of cable insulation resin generated from electric wires and cables was investigated. Conventional insulation PVC contains a lead component, tribase, as a thermal stabilizer and lead removal is necessary to recycle this PVC as insulation resin. This paper describes a solid surface adsorption method using ion exchange resin to remove the fine lead containing particles from PVC...

Natural fibrehas a good capacity as acoustic insulation materials because of its characteristics, and therefore it is widely used in many applications. This research aims to explore biomass waste from the palm oil mill coconut production materials. Fibre wastes for this study included empty fruit bunch (EFB), mesocarp fibre (MF) coir (CF), which were treated using sodium hydroxide (NaOH) elimin...

Abstract Nowadays, there is an increasing demand on environmentally friendly materials, so the conscious architecture and use of materials have also become preferred. It becoming increasingly important to turn from artificial products made renewable raw materials. The straw quilt, which considered be a new, innovative product Hungarian construction market, can provide alternative for this need....
