Método de avaliação de desempenho do comportamento de estruturas compósitas agrupadas por colagem submetidas à colisão com base em indicadores

Abstract

The recent statistics show a raise in the number of car accidents in Brazil. This way, the concern about the driver’s safety began to be each time more necessary. Besides, Brazilian cars have a lot of to develop compared to the American and European safety standards. Is possible to find that the suppliers have a high profit, in the other hand there are replacements that use fragile components, with low quality and have a lack of safety devices. This study aimed the performance analysis using process indicators of measurement, manufacturing, and the collision test of samples enhanced by carbon fiber, grouped using glue, whose are part of cars structure manufactured by the biggest supplier of automotive components in France. This project used analysis methods of performance that could evaluate the course of composite structures using the determined indicators, considering the receiving process of material by the supplier until the execution of the tests in the traction machine. Additionally this method allows verifying the most resistant thickness of glues in a collision, providing more safety for the users. Through the performance analysis was possible to conclude the efficiency of the method for the automobile industry and car users. The present study was able to prove that the method can be used in different kinds of material and for others companies in the automotive business.
