Prospecção de novos materiais para molas de suspensão automotiva

Abstract

Because of the technological revolution and current market demands, it is of great importance to be always one step ahead with technological innovations. But besides the technological advancements, the rising costs of fabrication the market of such products is always a concern. Thus, this paper is discussed a way of innovation in materials used for the manufacture of automotive suspension springs, suggesting the substitution of these materials for new materials that provide the properties and characteristics required by these springs. Therefore, also taking into account the cost of developing these products. It was used as a methodological resource, the literature, which proposed methods for the development of design and choice of material for the spring steel replacement for the manufacture of coil springs for automotive suspension. And the material that appeared more suitable for such applicability was the matrix composite epoxy and carbon fiber longitudinal. However, for cost reasons would be better applied in high-performance cars.
