Mechanical and Wear Characterization of Nano Based Calotropis Gigantea Fiber Reinforced Polyester Composites

Abstract

The growing interest on development of biodegradable materials led to growing concern about bio-based composite materials among the bio fibers applications one of the lightweight materials. Very minor research work is available in the mechanical characterization of CGF composites. In this paper the mechanical properties like tensile strength, flexural strength, impact strength and hardness of the CGF reinforced polymer composites were investigated. Also the impact of naturally modified montmorillonite (MMT).Nano clay on mechanical properties of the CGF composites was studied. The maximum volume fraction of the Specimens is 35%. The results demonstrate that the properties of nano-based CGF composites are better than the non-nano based composites. Tri-biological behavior of the CGF composites also studies and observed that nano CGF composites are having good wear characterization

CFD Simulation of Aerodynamics Truck Using Cylinder as Drag Reduction Device

“…This comparison examines the fuel required to overcome the vehicle's drag. According to Praveen et al, [5], the following equations can be used to express the relations between drag force and fuel consumption numerically…”

“…Components such as skirts on the sides and boat tails on the back of the truck can be added to reduce drag. By adding this component, research by Praveen et al, [5] and Landman et al, [6] was able to reduce the drag on trucks by 30 %. A windshield can also be added to the top of the truck to reduce drag.…”
