Crack bridging and trapping in borosilicate matrix composites with distributed metal particles

Original language description

One of the most efficient ways to improve the fracture toughness of ceramics is to reinforce them by large volume fraction of bonded metal particles The toughening effect of the metal particles was attributed to both crack trapping and bridging. While the bridging effect has been relatively well documented, the crack trapping effect is still somewhat inadequately understood. In contrast to crack bridging, the effectiveness of crack trapping increases with the debonding toughness of the particle/matrix interface. When the tough heterogeneities are equiaxed particles, adhesive strength becomes a very critical issue. Specifically, some optimum interface debonding is needed to remove the geometric constraint and allow the particles to deform plasticallyina significant part of their volume. The aim of the contribution is to confront the measured fracture toughness values obtained on borosilicate glass matrix composites with theoretical predictions.
