A commercially available amorphous metal ribbon incorporated into a glass‐ceramic matrix was assessed from the standpoint of fracture toughness. The ribbon orientation (with respect to the long and short transverse sides) relative to the opening crack significantly affected the fracture toughness of such composites. The strong dependence of the fracture toughness on the ribbon orientation was correlated with the differences in the bending contributions of the ribbons in the different orientations. The effect of the ribbon orientation on the crack growth rate in the matrix was also investigated.
