VIABILIDADE DO USO DE POLIAMIDAS NOS VEÍCULOS AUTOMOTORES

Abstract

The theme addressed in the work is about the feasibility of using polyamides in motor vehicles and the present objective of the study will be to analyze the feasibility of using polyamide in motor vehicles. To this end, the literature on the topic addressed was reviewed. Interest in the topic arose, since polyamides 6.6 and 6 and their types reinforced with glass fibers, and to a lesser extent the other polyamides, are considered the main engineering thermoplastics and with the use of polyamides in the manufacture of auto parts is it is possible to reduce the part weight, cost and time of manufacture. Of course, polyamides owe their importance not only to their good physical-mechanical properties, but also to the large-scale economy of production of their monomers used basically for purposes textiles, which make these thermoplastics competitive in cost / kilogram of resin, in relation to traditional metals (steel, aluminum, bronze, etc.) that it has been substituting in the area of ​​the automobile industry, electrical and household electrical engineering, light mechanical engineering and precision, standing out mainly for applications in external rear-view mirrors, panels, hubcaps, components for doors, windows, headlights, admission. It was seen that engineering thermoplastics have been shown to be a highly effective polymer, capable of replacing classic materials used in the manufacture of the automobile. Polyamide resins have several properties that make them one of the most noble, technical and versatile materials. At the end of the study, it was concluded that the replacement of metals by plastics is not only possible, but also widely used by the automobile industry today, due to the many advantages that these offer. In this work it was possible to evaluate some of the advantages that these substitutions can bring to the automobile. Thus, it was found that plastic parts, more and more, have their importance recognized as part of vehicles, enabling mainly economy, flexibility and safety for the final product.
