Michaelmas term. 13 lectures + 1 examples class + 10 hours coursework. Assessment: 75% exam / 25% coursework

Aims

The aims of the course are to:

  • develop a systematic approach to design with composites based on mechanical properties and to understand the practical considerations associated with design, manufacture and service requirements.

Objectives

As specific objectives, by the end of the course students should be able to:

  • be familiar with the range of composite systems in use.
  • derive and use formulae to bound composite material properties.
  • perform simple laminate analysis by hand, and more complex analysis with the help of appropriate software.
  • be familiar with the use of carpet plots to choose laminates based on stiffness.
  • understand the detailed mechanisms of lamina and laminate failure.
  • use strength models of failure for lamina and laminates.
  • describe design processes commonly used for composite structures.
  • be familiar with the manufacturing routes for composites.
  • use selection charts to select an appropriate manufacturing route.
  • understand the practical requirements associated with joining, manufacture and service use.
