摘要：

Dense carbon fiber-reinforced hBN composites were fabricated using reactive sintering aids, Si3NB4,SiO2 and Y2O3, by filament winding method followed by hot pressing in Nz flow. The most suitable temperature for fabrication was found to be 1800 degrees C. The bending strength of the composites at room and elevated temperatures showed excellent properties, namely, it increased enormously as test temperature increased. The strength at 1600 degrees C reached double of the one at room temperature.
