Fractographic techniques have been increasingly applied to failed specimens in attempts to define micromechanical failure mechanisms in composite materials. This effort can provide useful information relevant to all phases of studies of composite materials. For example, fractographic data obtained from laboratory control specimens can be used in material selection and optimization. Similarly, efficient structural design requires a detailed understanding of the fracture behavior of the material and the modes of failure of the component. Finally, as a production tool, microscopy can be applied to assess the quality of incoming material once key accept/reject features have been identified.
