March, 1997. Originai ar:icle submitted October l O, 1996. The effect of The dimensions of SiC whiskers on the stren~h and toughness of hot-pressed composites with a 20% volume fraction of whisker reinforcement was studied. It was established that the mechanical properties of the composites were improved only on introducing whiskers with the diameters within 1.5 - 2.5 gm. These materials also exhibited a higher resistance to crack propagation. Crystais orsmaller diameter had a negative effect on the mechanical properties, which was explained by bundle tbrmation. There is a definite criticai content of whiskers ensuring *,heiruniform distribution in the matrix, and this vaIue decreases on reducing the whisker diameter. A correlation was established between composite toughness and the level of average residual compressive stresses in the whiskers. I n t r o d u c t i o n . Re
