Study of Composite Helical Spring Using Glass Fibre with Araldite LY556 and XY54

Abstract:

This paper titled “Study of composite helical spring using glass fibre with Araldite LY556 and XY54”. Currently, the composite materials in the automobile sector are used for construction of the body, interiors, chassis, hoods, electrical components etc...these components are in simplest form and also they are regular in shape and easy to manufacture. However the design of suspension system and complicated structures in the automobile are quite difficult to bring out the same shape and performance. The most important no gap of steel springs suspension are limited corrosion resistance, long-lasting manufacturing process and weight. This paper brings out incredibly a simple method to prepare the composite helical spring for any dynamic application. The glass fibre and resin mixed with 70:30 ratio and it is tested by compression testing machine as per ASTM. The mechanical properties, such as maximum load carrying capacity, deflection, stiffness Youngs’modulus, Shear stress and strain energy are determined using compression testing machine. The objective of this study is to reduce the weight of the spring, to obtain good surface finish, similar to steel spring, novel manufacturing methodology and identification of failure point rather than the maximum load.
