Analytical Characterisation of Composite Materials S7
Module aims
This module introduces the various types of advanced analytical techniques used to characterise the properties of polymers, fibres and fibre-matrix interfaces, building upon the unique expertise within the Department. We will cover various spectroscopic, surface & interface, and thermo-mechanical characterisations suitable for characterising polymer composites. Analytical techniques suitable to characterise the bulk properties of polymer composites will also be covered in this module. For each of the analytical characterisation technique discussed, a basic understanding will first be provided, followed by an in-depth discussion of what the data and results mean. The real world applications of the analytical characterisation techniques are also covered in this module. Ultimately, students will be able to adapt and expand these advanced analytical characterisation techniques for various advanced materials beyond polymer composites. The content covered in this module is particularly suited for students who (i) aims to pursue a doctoral degree in materials-related subjects or (ii) intend to work with materials.

Teaching methods
The module will be delivered primarily through large-class lectures introducing the key concepts and methods, supported by a variety of delivery methods combining the traditional and the technological. The content is presented via a combination of slides, whiteboard and visualizer. Learning will be reinforced through tutorial questions.
