Abstract: Natural fibres have attracting the interest to engineers, researchers, professionals and scientists all over the world as an alternative reinforcement for fibre reinforced polymer composites, because of its superior properties such as high specific strength, low weight, low cost, fairly good mechanical properties, non-abrasive, eco-friendly and bio-degradable characteristics. In this point of view, a brief review has been carried out to make use of natural fibres (such as abaca, banana, bamboo, cotton, coir, hemp, jute, pineapple, sisal etc) abundantly available in India. Glass Fibre Reinforced Polymers are mixing with natural fibres to increase Engineering and Technology applications. This paper presents a review on the mechanical properties of natural-glass fibre reinforced polymer composites.

Abstract: Many researchers have used coal fly ash; rice husk ash, nano material and conducting polymer- as adsorbents to remove water pollutants including Cr, Pb, Hg, Zn, Mn and Cu, heavy metal. The main objective in this study to identify the nano materials used for heavy metal adsorption process effectively. The different parameters, pH, contact time etc. which affect the adsorption process. By reviewing this paper to find out the scope of conducting polymer based nanocomposite for heavy metal removal in aqueous system.

Abstract: The applications of aluminium matrix composite materials are growing continuously in the field of automotive and aerospace because of their superior physical, mechanical and tribological properties as compared to base alloy. Composite materials with metal matrix material e.g. aluminium or magnesium are finding broad level applications in many industries because of their lower density, better wear and corrosion resistance, high strength to weight ratio, good formability, high hardness, high thermal shock resistance, high modulus, high fatigue strength etc. In automotive industry they are being used in various parts e.g. pistons, cylinders, engine blocks, brakes etc. Aluminium based composites reinforced with micro/nano SiC, Al2O3, B4C, TiB2, ZrO2, SiO2 and graphite particles, changes the micro-structural characteristics that develop superior mechanical and physical properties appropriate for automotive/aerospace applications.

Abstract: Complex aerodynamic design, high mechanical and thermal loads, extreme environmental and other service conditions produces high magnitude of dynamic stresses in various components of airframe. The magnitude and nature of these stresses further varies during different phases of flight. This governs the need to develop special materials having ability to withstand these variable stresses. Further high fuel costs, scarcity of raw material sources, need of efficiency improvements, growing demand of new aircrafts (both military and civil) and raised environmental standards (less CO 2 emission, less noise pollution, recyclability of materials, etc.) are the few factors which forced the engineers to make stronger but ‘as-light-as-possible’ engine, frame and other parts of aircrafts. These factors open the door for ‘stronger-but-lighter’ metals like titanium and its alloys for aerospace application segment. Titanium and its alloys offers a unique set of physical, mechanical, metallurgical and composite compatibility characteristics which helps the aerospace sector to meet economy, fuel efficiency and other global standards in a wide range of temperatures and other service conditions. Starting from its first application in 1950s to till date, this wonder-metal not only increases its share of presence but becomes the first choice of aircraft fabricators. This paper presents an overview of inherent mechanical and metallurgical characteristics of titanium and its alloys which makes it an ideal for the aircraft applications. A brief summary of induced stresses in aircraft critical components with advantages of titanium and its alloy to manufacture these components is also discussed.
