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,
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
