Abstract : Practical design criteria and the structural significance of defects and damage in carbon fibre composite components are briefly reviewed. Consideration is given to the principal sources of in-service damage and the possibility of the interaction of damage mechanisms. The concept of providing a map of damage acceptability for a given structure is then discussed. An assessment is made of the probable current requirements for in-service NDI, the capabilities and limitations of currently available NDI techniques are reviewed and some recent developments described.
