FRASTA (fracture surface topography analysis), a newly developed fractographic technique that shows how a crack front interacts with microstructural features, is described and applied to a continuous fiber-reinforcd intermetallic matrix composite. The fracture surfaces of a tensile specimen were examined and their topographies quantified. The fracture process was reconstructed in microscopic detail by comparing the conjugate topographic features at various relative displacements using FRASTA. The results show the sequence of microfailure events occurring in the matrix, in the fiber, at the fiber/matrix interface, and in the fiber core, and hence they provide information useful for developing composite materials that promise to be more resistant to failure.
