Mixed zirconium powders are inorganic ceramic materials containing zirconium elements.Mixed zirconium ceramic powders-ZrO2,ZrB2,ZrC and ZrN were prepared by sol-gel and carbothermal reduction methods,and were coated onto the carbon fiber surface using continuous sizing process.The structures and components of mixed zirconium powders were analyzed by X-ray diffractometer.The effects of the addition of mixed zirconium powders on the morphology and heat resistance of carbon fibers were studied by scanning electron microscope and thermogravimetric analyzer.The results showed that the optimum experimental conditions for synthesis of mixed zirconium powders were as follows:sintering temperature was 1600℃,and material ratio was n(Zr)∶n(B)∶n(C)=1∶2.5∶12,when the ZrB2 content in the powders was relatively the most.After being modified by 10% powder sizing,the initial oxidation temperature of carbon fibers increased from 675.1℃ to 717.9℃,and the apparent activation energy of oxidation reaction increased 76.41kJ/mol to 115.43kJ/mol.
