Extracted text: Describe three of the functions of the matrix in fibre- reinforced composites. With the aid of sketches compare and contrast the fatigue fracture appearance between an alloy that failed at a low fatigue load and one that failed at a high fatigue load. Propose and briefly describe one non-destructive method that can be used to detect small cracks on the surface of a metallic alloy.
