摘要：

Toughening achieved by incorporation of whiskers to ceramic matrices was calculated based on an approach that combines individual contributions from effective toughening mechanisms. The relative importance of each mechanism, among others, was found to substantially vary depending on the selection of whisker and composite parameters. Analysis of the effect of various parameters showed that whisker strength, pullout length, debond length, and volume fraction of whiskers are the most important parameters in whisker toughening. Very good agreement was found between predictions made by the combinatory approach and experimental toughness values of Al2O3/SiCw composites.
