The feasibility of producing metallic-glass ribbon reinforced glass-ceramic composites by low-cost pressing and sintering techniques was demonstrated. The quality of the composite specimens produced was affected by factors such as binder content, compaction pressure, and sintering temperature. The mechanical behavior of such composites was studied and the failure modes could be correlated to variations in the matrix strength and interfacial bond strength with temperature. The fracture toughness of such composites was dependent on the ribbon orientation (with respect to its long and short transverse faces) and ribbon layout in the matrix. The load-transfer characteristics of this composite system was found to be different from those of other fiber-reinforced systems. Discontinuous metallic-glass-reinforced glass-ceramic matrix composites were also fabricated. The mechanical strength of such composites was found to be within 80% of the strength of a continuously reinforced composite containing the same volume fraction of reinforcements. The strength of such composites was also found to be isotropic in the plane of compaction.
