Abstract(s)
Atualmente, devido às preocupações com a ecologia e sustentabilidade procuram-se
modernizar ou criar novos métodos de mobilidade na vida quotidiana. Uma das principais
indústrias que permite atender estas preocupações é a ferroviária, ao que a sua modernização
a nível nacional tomou novas proporções com o aumento do investimento. Esta modernização
tomou por caminho a disseminação generalizada do uso de materiais compósitos nesta
indústria, que atualmente é reduzido. A presente dissertação teve como objetivo principal a
avaliação do fabrico de componentes para material circulante ferroviário em material
compósito, através do processo de fabrico de infusão a vácuo. Esta dissertação desenvolveu-se
em contexto de estágio no INEGI. De maneira a possibilitar o cumprimento do objetivo
desenvolveu-se um estudo do processo de fabrico através da sua aplicação e subsequente
avaliação através da caraterização mecânica e física dos materiais compósitos obtidos.
Analisou-se a aplicabilidade do processo de fabrico e os seus resultados durante o
procedimento experimental deste. Avaliaram-se as propriedades mecânicas através da
realização de ensaios de tração, e as propriedades físicas por meio de ensaios de queima e de
ensaios de micrografia. Os resultados obtidos por estes ensaios foram analisados, ao que se
conclui a viabilidade do fabrico de componentes para material circulante em material
compósito pelo processo de fabrico de infusão a vácuo e determina-se qual o melhor material
compósito para a aplicação.
Currently, due to concerns about ecology and sustainability, there are attempts to modernize or create new methods of mobility in everyday life. One of the main industries that can meet these concerns is the railway industry, whose modernization at a national level has taken on new proportions with the increase in investment. This modernization has led to the widespread use of composite materials in this industry, which is currently limited. The main objective of this dissertation was to evaluate the manufacturing of components for railway rolling stock in composite material, through the vacuum infusion manufacturing process. This dissertation was developed in the context of an internship at INEGI. To achieve the objective, a study of the manufacturing process was developed through its application and subsequent evaluation through the mechanical and physical characterization of the composite materials obtained. The applicability of the manufacturing process and its results during the experimental procedure were analyzed. The mechanical properties were evaluated through tensile tests, and the physical properties through burning tests and micrograph tests. The results obtained by these tests were analyzed, concluding the feasibility of manufacturing components for rolling stock in composite material through the vacuum infusion manufacturing process and determining the best composite material for the application.
