Abstract : The significance of defects in composite aircraft structures is described from a broad, practical viewpoint. The description is organized by concentrating on three generic defect types (cut fibers, matrix cracks, and delaminations) and on simple load components that can be generalized to the most complex loading cases. Methods for evaluating manufacturing and in-service damage in terms of the resulting local damage are reviewed. In addition, the possible benefits of more damage tolerant forms of composite materials are explored.
