Content | The course will comprise a balance of lectures, tutorials, student presentations and laboratory classes. In addition, case study site visits will be made for certain topics to illustrate the industrial application of particular technologies. More and more, the interest in particle and fibre reinforced / structural composite materials is increasing. In beginning, the main focus will be on the production of functional fibres, e.g., for fibre-based sensor and actuator composites with polymers, metals and ceramics. Optical, piezoelectric, shape memory and other fibres for advanced composite applications will be treated in detail. There will be a discussion on fibre classification, fibre production (ceramic and others), adaptive and smart materials, types of sensors and actuators (e.g. made from electro-active polymers), and sensor networks with piezoelectric composites (e.g., Active or Macro Fibre Composites) for adaptive material systems or structural health monitoring (SHM) of advanced composite structures. Furthermore, students will get an overview of biomedical composites and composite application in the field of aerospace, automotive, civil engineering, and energy industry. Emphasis will be put on the underlaying science of a particular process or effect rather than a detailed description of the technique or equipment. Manufacturing of actuators driven by electro-active polymers (EAP) and sensors applications of Active Fibre Composites (AFC) will be studied in laboratory classes. Case studies and examples drawn from structural and functional applications of advanced composite and adaptive material systems will be demonstrated. | ||||
