Preparation of Fe/Ti/Al Nano-particles and Mixed Nano-composites from Aluminium Industrial Wastes
Abstract: AbstractIndian alumina refineries produce over 6 million tonnes of alumina generating about 9 million tonnes of bauxite residue commonly (known as red mud) per annum, typically containing 50–60% Fe2O3, 15–20% Al2O3 and 3–5% SiO2, TiO2 and Na2O. Efforts have been made to synthesize nano-particles (Fe/Al/Ti) and nano-composites (Al-Fe-Ti/Al-Fe/Al-Ti) using red mud for chemical precipitation and mechanical milling. XRF was used to check the chemical composition of red mud processed at …

Characterization of Glass/Jute Hybrid Fibre Reinforced Epoxy Composite for Axial Flow Fan Blade
Abstract: Traditionally axial flow fan blades were manufactured by using metal alloys, but with the increase in blade size the blades grew heavier resulting in more vibrations during its working. It is impossible to manufacture the metallic blades to close tolerances making it uneconomical. Due to this dimensional instability, the metallic impeller fan blades are instead fabricated with glass fiber reinforced plastics (GFRP). To reduce the after effects of GFRP blades …
