Abstract: Si-Zr-C-O fibre (Tyranno ZMI®fiber)/SIZrC mincomposites dispersed ZrSiO₄ particles in the matrix were fabricated by the PIP (Polymer Impregnation and Pyrolysis) method. The minicomposites with 30wt% ZrSiO₄ particles in the matrix showed extremely high tensile strength up to 1573K in air than when otherwise. From the observation of microstructures of the minicomposites with dispersed ZrSiO₄ particles, it is found that any fibre did not contact each other within a distance of a few micrometers in the matrix. In addition, the matrix included fewer cracks and was of apparently higher density than those of the matrix without ZrSiO₄ particles. ZrSiO₄ particles dispersed matrix was applied to the 2D composites.

Keywords: ceramic matrix composites; CMCs; polymer impregnation and pyrolysis; PIP; ZrSiO₄ particles; tensile strength.
