摘　　要：应用不同质量比的甘蔗渣和环氧树脂进行复合、热压,经真空烧结后,制得甘蔗渣基木陶瓷.利用TG-DSC对甘蔗渣基木陶瓷的热分解行为进行初步分析,利用XRD,SEM表征了所制备的木陶瓷的相组成和微观结构,研究了甘蔗渣用量对开口气孔率及摩擦性能的影响.结果表明:甘蔗渣基木陶瓷具有生物管状的多孔结构;随着甘蔗渣用量的降低,木陶瓷的石墨化程度略有提高;木陶瓷的开口气孔率随甘蔗渣用量减少而减小;摩擦系数随转速的增加而增大,随载荷的增大而减小.当甘蔗渣/环氧树脂质量比为1∶1时,木陶瓷的开口气孔率为35.12%,摩擦性能最好.The bagasse-based woodceramics were prepared with different proportion of the bassage and epoxy resin in vacuum tube at high temperature after hot-pressing.Themogravimetric and diffential scanningcalorimeter analysis（TG-DSC） were applied to reveal the pyrolysis behavior of the bagasse-based woodceramics.Woodceramics were investigated by x-ray diffraction（XRD） and scanning electron microscopy（SEM）.The effects of the bagasse amount on the friction properties and the appareant porosity were studied.Experimental results show that the bagasse-based woodceramics have biological tubular porous structure.With the decrease of the bagasse amount,the graphitization degree of woodceramics increases.The appareant porosity of woodceramics becomes smaller with the decrease of the bagasse amount.The friction coefficient of the woodceramics increases with the increase of the rotation speed,but the friction coefficient decreases with the increase of the load.When the mass ratio of epoxy resin and bagasseis 1,the apparent porosity of woodceramics is 35.12% and the friction property is the best.
