| dc.description.abstract | The main objective of this thesis is development of composite helical coil spring for light weight vehicle. The candidate materials are E-Glass, Carbon fiber and Epoxy resin. The selection of an appropriate weight fraction for both chopped carbon and glass fiber composition between 0.4:0.6, 0.5:0.5, 0.6:0.4 is conducted through analytical (Advanced rule of mixture) and laboratory experiment (Tensile testing machine. Chopped carbon fiber with 0.4 weight fraction of epoxy resin and 0.6 weight fraction of fiber composition is selected for our spring through composition property of the composite material. The 3D model has done using SOLID WORK 2016. The equivalent elastic strain and maximum stress were considered at the static condition using ANSYS 2016. The static analysis were developed using fixed support on the lower end of the spring. Comparison has been done in terms of stiffness, deflection, specific strain energy, and strength to weight ratio of the spring for each spring using chopped carbon and glass fiber, and the composite chopped carbon fiber with 0.4:0.6 composition is found to be better with the desired property of a spring material compared with conventional structural steel and glass fiber. | en_US |
