摘要:
Ultra-high temperature ceramic matrix composites (C/SiC-ZrB2) are prepared by slurry infiltration and precursor infiltration and pyrolysis method. C/SiC-ZrB2 composites with ZrB2 volume content from 10% to 24.6%, have balanced performance of fracture toughness (17.7-8.1MPa-m(1/2)), flexural strength at room temperature (366.7-162.8MPa) and at high temperature (strength retention 74.1% at 1800 degrees C and over 31.8% at 2000 degrees C), better anti-oxidation, anti-ablation under oxyacetylene torch environment (recession rate 0.01mm/s).
