Abstract
Nowadays, many industries are shown interest in the hybrid composites, natural fibers, and reinforced materials due to reduction of the weight. The reason is that it will not affect environmental conditions. This experimental investigation identified the mechanical properties of hybrid composites. The hybrid composite materials are extensively used by E-glass/epoxy, carbon, and titanium alloy. Composites have good strength and less weight. The highest challenge of the automobile industry is to replace the steel leaf spring instead of the composite leaf spring. The composite structures have been providing better corrosion resistance. The conventional leaf spring experimental results were compared to analytical results of composite leaf spring. The design, simulation, and maximum stresses were done with the help of Ansys Workbench 15. Ansys Workbench materials are selected by titanium alloy, epoxy glass, aluminum alloy, and epoxy carbon. The design parameters were selected and analyzed to compare stress, deformation, elastic strain, and weight of the composite leaf spring as compared to conventional steel leaf spring. Deflection results were identified in the mechanical properties of the leaf spring. It should absorb shock loads and vertical vibrations due to road abnormalities. The composite experimental samples were analyzed using scanning electron microscopy.
Highlights
A leaf spring is mostly used by stainless steel in all the vehicles
The supported type is used for the first method, in which all the sides of the leaf spring are attached to the vehicle chassis (Das 2011)
The second method, used for cantilever type of leaf spring, is fixed in one end of the vehicle chassis and the last end is attached for free displacement
Summary
A leaf spring is mostly used by stainless steel in all the vehicles. The leaf spring arrangements are divided into two different methods in automobile vehicles. The tensile properties have been evaluated and identified better layer structures combination of composite layers. They proved the tensile test results develop better performances from the fiber/matrix adhesion. The hybridization effect on the curaua fibers and glass combinations identified the adhesion strength for the tensile properties. Rahmat and Hubert (2019) developed the jute/glass fiber mixed composite structures and identified its bonded effects with molecular strengths. It identified the tensile, impact and flexural strengths for adhesion of better joint solutions, but degreased the water absorption levels and stages from the composite structures. All the equivalent structures and mechanical arrangements were done by composite added fibers
