This paper deals with the applicability of fiber reinforced plastic in springs. Three different types of springs were manufactured using glass fiber, carbon fiber and glass/carbon fiber in +45 degree orientation. Tests were conducted on the springs to study the mechanical behavior. The spring rate of the carbon fiber spring is found to be 24% more than the glass fiber spring and 10% more than the glass/carbon fiber spring. Stresses acting on the composite springs were less compared to steel spring. The weight of the composite spring is almost 70% less than that of the steel spring. The specimen preparation and experiments were carried out according to ASTM standards.
