Abstract
Leaf Spring is one of the oldest components widely used in commercial vehicles due to easy manufacturing cost and better load carrying capacity. Due to heavy competitive market and strict rules from governments, automakers want to reduce pollution, fuel consumption etc. Further weight reduction is the most effective way of improving fuel economy without losing the performance of the vehicle. So, usage of Composite Materials is gradually increased in the Automobile Industry. In the beginning, Composites are used only for decorative purposes. But recently composites have been used in structural parts also. Some Sports car manufacturers even make an entire automobile body out of carbon fibre. Coming to Leaf Spring, Steel is still preferred due to its high strength and Energy Absorption Ratio etc. The applications of hybrid composite materials in various fields formerly cannot achieve using conventional materials. In this research article, Carbon/Glass Epoxy Composite is proposed as leaf spring material. The specimen is fabricated and mechanically tested for tensile strength, Impact Strength and Flexural Strength. Also, Solid modelling of Leaf Spring is done using SolidWorks 2014 and FEA is done using ANSYS 16.2. Results are documented, compared and discussed.
