【摘要】

：

本文使用硅烷偶联剂KH550对介孔分子筛MCM-41进行表面修饰后添加到环氧树脂中，制备得到环氧树脂/MCM-41复合材料。采用热分析、扫描电镜、傅里叶红外光谱、X衍射、氮气吸附-脱附等手段对表面修饰前后的MCM-41进行结构表征，并对复合材料的力学、热学和电气性能进行测试。本文利用差示量热扫描仪熏点研究了环氧树脂/MCM-41复合材料的固化动力学，通过n级模型得到复合材料固化过程的反应级数、活化

大尺寸Nano-SiCp/AZ91D镁基复合材料的组织及其力学性能

采用超声波辅助搅拌铸造的方法，制备了体积分数为1％的纳米SiCp/AZ91D镁基复合材料的大尺寸铸锭。对其不同部位的组织进行观察发现，大尺寸铸锭外侧纳米颗粒分布相对内侧更为均匀，并且，不同部位的晶粒尺寸存在显著差异，铸态复合材料外侧上部晶粒相对内侧下部晶粒更为细小。复合材料不同位置颗粒分稚情况存在较大差异，部分位置可以观察到明显的团聚现象。力学性能测试结果表明：铸态复合材料外侧中部的力学性能最优，

针叶树材木质素基碳纤维的力学性能

为提高针叶树材木质素基碳纤维的力学性能,通过熔融纺丝法制备的聚乙二醇木质素纤维先经过85℃的lHC1与C6H12N4混合水溶液化学固化lh,再在空气氛围中以一定的升温速率从室温加热至250℃氧化热稳定处理,制备得到无表面缺陷的不熔融纤维和经碳化后的碳纤维.研究表明,在化学固化过程中,由ChH12N4分解得到的甲醛分子在木质素分子中的苯环之间形成亚甲基键连接,提高了水质索分子的交联程度,并且在纤维表

木材液化物水洗不溶物的制备及其性能研究

本论文对术材液化物水洗不溶微球进行了研究，利用不同洗涤工艺可制备木材液化物微球，并对其微观结构、热性能、化学结构进行了探讨和分析。结果表明，水浴温度70℃的中性水水洗工艺制备的杉木、杨木液化物微球在数量、球形度、表面致密性等方面均优于常温水水洗工艺和盐酸水溶液洗涤工艺，前者的灰份含量则低于后两者。
