Experimental Investigations on Torsion Damping and Machinability of Fiber Reinforced Polymer Composites Using Sensors Signal Analysis

Abstract

In recent days, most of the engineering sectors like aerospace, automobile, and marine are seeking for light weight components to increase the efficiency of the system. To achieve better outputs, they are replacing metal components with fiber-reinforced polymer composites (FRP). The reason for the selection of composites is lesser weight and high mechanical properties. FRP composites are used in automobile sector products like car bonnets, doors, bumpers, and structural components. Some of the rotational components are still made of metal matrix composites and the researchers are carried out to replace them using FRP composites. However the fabrication of FRP and pridecting the failure and understanding the mechanical behavior of FRP shafts is a difficult process. The evoluation of polymer matrix and fiber orientation of composite materials has a major impact on the mechanical properties, especially the torsional ability of polymer composites. In this research work, the spirally stacked basalt and glass fiber polymer composite rods were fabricated using the vacuum-assisted resin transfer molding method (VARTM) to study the torsional behavior under static torsional loading conditions newline
