These studies focus on improvements in the mechanical performance of ceramics by consideration of composite toughening approaches. Analysis of toughening processes indicated that both crack deflection and whisker pull out mechanisms can contribute to the fracture toughness of ceramics which contain strong small diameter whiskers. Results show that these processes can indeed yield high toughness in SiC whisker reinforced ceramics.
