Abstract : The significance of defects and damage in fibre composite structures depends upon a wide range of decisions taken at every stage of the life of each particular structure, from the initial design conception, through detailed design and manufacture, to inspection, maintenance and repair procedures. Since many of these decisions interact, there is a need for a coherent overall philosophy for the management of defects and damage if fibre composite structures are to be efficient and cost-effective. In the present Paper the general requirements of such a philosophy are considered and it is seen that further research is required particularly on the interaction of defects and damage with structural features. Some initial results and observations from the RAE programme devised to study such interactions are presented.
