Esta dissertação foca-se no projeto e montagem de uma máquina de slitting para fitas compósitas de fibra de carbono com matrizes termoplásticas. O objetivo foi aplicar a um equipamento preliminar a funcionalidade de cortar fitas compósitas em larguras específicas, de modo a garantir a precisão e eficiência operacional. Para isso, começou-se por caracterizar o equipamento preliminar bem como a proposta de sistema de corte já existente. Depois, na fase de anteprojeto, foram apresentadas várias soluções construtivas dos componentes mecânicos, como o sistema de acoplamento das facas, o sistema de fixação do sensor ultrassónico e o
sistema de guiamento das fitas. Ainda no anteprojeto, foram estabelecidos os princípios de funcionamento tanto do sistema elétrico como do controlo da máquina. Na fase de projeto, foram desenvolvidos os dimensionamentos dos sistemas mecânicos e elétricos, e elaborados os desenhos técnicos. O sistema elétrico foi desenvolvido com medidas de segurança, incluindo circuitos de paragem de emergência e sistemas de barramento para garantir uma operação segura. Um sistema de controlo, com recurso a um controlador lógico programável (PLC), foi implementado para gerir a tensão e o alinhamento da fita, bem como o processo de corte. Foram realizados testes na máquina que validaram a sua funcionalidade no processo de slitting.
This dissertation focuses on the design and assembly of a slitting machine for carbon fiberreinforced composite tapes with thermoplastic matrices. The objective was to adapt a preliminary machine to incorporate the functionality of cutting composite tapes into specific widths, ensuring precision and operational efficiency. The process began with the characterization of the preliminary equipment, as well as the evaluation of the existing cutting system proposal. During the conceptual design phase, several constructive solutions for the mechanical components were presented, such as the knife coupling system, the ultrasonic sensor mounting system, and the tape guiding system. Additionally, the operating principles of both the electrical system and machine control were established during this phase. In the detailed design stage, the mechanical and electrical systems were dimensioned, and technical drawings were prepared. The electrical system was developed with safety measures, including emergency stop circuits and busbar systems to ensure safe operation. A control system, using a programmable logic controller (PLC), was implemented to manage tape tension and alignment, as well as the cutting process. Tests were conducted on the machine, which validated its functionality in the slitting process.
