Modelling, Analysis, Fabrication and Experimental Testing of Leaf Spring Material by Hybrid Composite Materials with Natural Fiber for Electric Vehicle

Abstract

Present automobiles are running with the help of fuel. But in the future, electricity plays a significant role. The generation upgrading into electricity as the main source. Leaf springs are used for suspension for automobiles. These leaf springs are manufactured with stainless steel material. This is heavy in weight, which is one of the limitations for consuming of fuel. If this material is used in electric vehicle, it consumes more electricity. To overcome this issue the material is replaced with composites. The primary goal of this endeavour is to achieve weight rebates without diminishing in reliability. A parametric study of the leaf spring by varying the three-dimensional parameters will be carried out. Fabrication of the composite specimen is based upon the ASTM standard. Modelling and analysis of composite leaf spring with SOLIDWORKS and ANSYS WORKBENCH software. Epoxy resin and E- glass fibre is reinforced with various fractions of Prosopis Juliflora (Throne powder) composites were falsification by hand layup technique. The fabricated composite material in the form of plate were cut into corresponding profiles as per ASTM standard. The objective is to examine the Stress, Strain, Deformation, Physical property, Mechanical properties, Thermal property of composite leaf spring with that of steel, CFRP.
