Abstract
The automotive industry is always investing in materials in research and new resources that improve vehicle performance or production cost, and resources can even be materials, often with the use of composite materials. This study aimed to improve the protection of the CVT pulleys of the service proposed by the Caraubaja SAE team, from the Universidade Federal Rural do Semi-Árido - UFERSA, Caraúbas campus, in order to improve its resistance and durability and reduce the mass added to the part. The work was developed to evaluate the feasibility of the protection to be reinforced with a composite material with fiberglass fabric and aramid fabric with an epoxy resin matrix. For this replacement to be viable, the material must have mechanical mechanics or equal to 1010 steel, as required in the regulation of the larger competition, SAE Brazil. The work was based on an impact test performed on specimens previously laminated manually by the Hand Lay-up process and curing took place at room temperature, between 25-30ºC. The test to determine the mechanical resistance to impact used was Charpy and the specimens were constructed according to ASTM D6110 (2010) for composites in two configurations (2 layers of glass / 6 layers of aramid /2 layers of and 2 layers glass/8 layers of aramid/2 layers of glass), 2.57 mm and 3.28 mm thick, respectively. The results obtained for the two sets of specimens were analyzed and compared with 1010 steel, in order to evaluate the feasibility of manufacturing the part with composite material. In view of the expected results of SAE 1010 in the protection of the CVT, the proposed resistance steel protection was not obtained. However, the study of formulating a new configuration, theoretically a proposal to replace generating materials.
