Course overview

All load-bearing structures are prone to some form of damage or defects.  In particular composite structures have very different defect types and the damaging mechanisms and effects are quite different to those found in metal structures.  Because of the laminated nature of composite materials, the through-the-thickness resistance to damage is often low, relative to traditional metal structures.   The composite structure is also a heterogeneous material and thus can be damaged at the constituent level (resin and/or fibres).  The biggest challenge is finding the damage/defect and determining the damage/defect influence on structural performance and integrity.  Then determining the best repair approach to restore the structure to full operational capabilities is much easier to identify.

This workshop will

  • review the basics of composite material constituents and fabrication process to aid in how damage is inflicted, found and in determining the stress state of the damage/defect region.
  • provide a detailed description of the various types of damage/defects found in composite materials is provided and how the geometry of the non-conformity, loading conditions and local environment effect the damage/defect behaviour.  Damage and defects are then categories into four basic types.
  • review the several common and developing NDI techniques in terms of what they tell you and how to interpret the results.
  • review the stress analysis approach used to consider the loss of structural integrity and develop a repair scheme.
  • provide an indepth overview of the four fundamental repair schemes for composite structures.  Each repair scheme is described in detail and the design/stress analysis methodology is reviewed.   The practical steps in repair application for composite materials is identified.
  • provide participants with a list of guideline questions to aid in the development of effective and efficient composite repairs.
