为了探讨烧结温度对纤维增强木材陶瓷界面结构的影响,用液化木材和炭粉制备片状基体材料,并通过酚醛树脂与碳纤维复合、在不同的烧结温度条件下制备碳纤维/层状木材陶瓷复合材料。利用扫描电镜(SEM)、场发射透射电镜(FETEM)、显微拉曼光谱(MRS)和X射线光电子能谱(XPS)等方法对其界面结构进行测试与表征。结果表明: 在基体材料中,无定形碳与玻璃碳相互融合,界面区过渡自然,无明显界限; 而在碳纤维与玻璃碳所形成的界面区中,较高的升温速度易形成为裂纹而呈现弱界面结合。同时,随着烧结温度的升高,界面区中有石墨微晶生成,但呈现出湍层结构。较高的烧结温度有助于脱除N、O、Na等元素,并有利于形成...

In order to discuss the effect of sintering temperature on interface structure of fiber-reinforced woodceramics, the flaky matrix was prepared from liquefied wood and carbon powder, and then compounded with carbon fibers through phenolic resin and sintered at different temperatures to obtain carbon fiber/laminated woodceramics. Scanning electron microscopy (SEM), Field emission transmission electron microscopy (FETEM), Micro-Raman spectrum (MRS) and X-ray photoelectron spectroscopy (XPS) were used to detect and describe the interface structure....
