Properties of Si-Zr-C-O fibre/S1ZrC composites dispersed ZrSiO_{4 particles in the matrix

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.
