| 摘 要： | 研究了短纤维增强玻璃陶瓷基复合材料制备工艺中的短纤维分散和单向纤维预浸片制备。结果表明: 在聚乙稀醇水溶液与乙二醇的混合分散介质中, 采用搅拌法可以得到短纤维的均匀分散, 分散介质的触变性对于均匀分散体系的获得与保持是十分必要的; 流延法有利于控制短纤维预浸片中纤维的取向。单向预浸片热压获得了高强韧性的复合材料试样。

| Abstract: | The fabrication processing of unidirectional short carbon and Nicalon fiberreinforced LAS composites was investigated. The parameters influencing dispersion and orientation of short fiber were discussed. It is shown that homogeneity of dispersion of short fibers was much better by stirring in mixing solution of ethylene glycol and aqueous polyvinyl alcohol solution than by other methods. Unidirectional alignment of short fibers in prepreg could be obtained by doctorblade casting. The samples fabricated in the study have excellent strength and toughness. |
