| Abstract: | Ceramic matrix-whisker composites can be strengthened and toughened with the mechanisms such as load transfer, matrix prestressing and crack deflection, fiber pullout and wake toughening. It is an effective way to improve the brittleness of high temperature structure materials. In this paper, the selection criterions of ceramic matrix and whisker, and the difficulties in studying and processing composites have been reviewed. The existing situation of typical composites is introduced, and some new research topics are suggested. |
