摘要(Abstract)：

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C-C结构。

关键词(KeyWords)： 碳纤维/木材陶瓷;烧结温度;界面结构;影响因素
