Abstract

The results of a systematic study of the effects of reinforcement architecture on the fatigue and fracture behavior of MoSi₂/Nb composites are presented. These include experimental and analytical results obtained from detailed studies of crack growth and crack-tip shielding mechanisms in composites reinforced with Nb particles, fibers and laminae. The crack-tip shielding contributions from crack bridging and crack-tip blunting in fiber-reinforced and laminated composites are analyzed using micromechanics models. Similarly, the toughening due to deflection by continuous tilting and twisting of cracks around the interfaces of particulate-reinforced composites is also assessed using fracture mechanics models. Superposition concepts are then used to obtain predictions of fracture toughness. The paper highlights the importance of composite architecture in the development of composites with improved fatigue and fracture resistance.
