Exclusions
Description This module will provide an introduction to fibre reinforced organic matrix composites and optical fibre sensors. With reference to fibre reinforced composite materials, the lecture series will provide basic information on the constitutive materials and their mechanical, chemical and physical properties. Non-destructive techniques will also be covered briefly. Emphasis will be placed on linking the processing chemistry to the design and deployment of optical fibre sensors. Strategies for selecting manufacturing techniques for fibre reinforced composites will be covered. Demonstration will include vacuum bagging, autoclaving and filament winding.
With reference to optical fibre sensors, this module will provide a basic introduction to optical fibres and as to how the properties of the light-guides can be modified or engineered to design sensors. The sensors systems to be addressed will include intensity and interferometric devices. The construction of sensors for monitoring strain, temperature, vibration and specified chemical species will be considered. The demonstration for this element of the module will include infrared spectroscopy using optical fibres and the associated sensors and light sources. The students will be given hand-on experience on handling fibres and in constructing specified optical fibre sensors.
Learning Outcomes

By the end of the module students should be able to:

  • Review the types of reinforcing fibres and organic matrices available for composites.
  • Define terms such as load-transfer, critical length, coupling agents and cross-linking.
  • Review conventional techniques for processing composites and test methods to assess the properties of composites.
  • Explain typical damage initiation and propagation modes in composites.
  • Describe the latest technology associated with optical fibre, sensors and associated instrumentation.
  • Discuss how the properties of the light-guides can be used to construct sensors for process monitoring of composites and also to assess the structural integrity.
