A series of 0, 10, and 25 vol% metal particulate/glass matrix composites in which the volume fraction of composite was both constant and graded across the specimen were prepared. Double-cantilever-beam fracture toughness results show that the graded fraction composites generally had equivalent values to the constant fraction specimens despite lower overall volume fraction particulate phase and composite density. Additionally, these results indicate the existence of a minimum composite layer thickness necessary for maximum toughening.
