摘要:

为牵引和推动国产碳纤维及其织物在复合材料液体成型技术中的进一步应用,对国产CCF300碳纤维表面特性、CCF300 45°/-45°和CCF300 0°/90°两种非屈曲经编织物(NCF)的编织工艺性、铺覆变形性以及NCF织物增强复合材料的力学性能进行了系统表征。研究结果表明:国产CCF300碳纤维表面物化活性较高;CCF300 0°/90°编织织物的编织工艺更稳定;NCF织物增强复合材料具有与单向织物增强复合材料相当的力学性能,同时兼具良好的结构稳定性、铺覆性和成型性,具备成为复杂形状预成型体的可行性。

Abstract:

Surface features of domestic CCF300 carbon fiber, manufacturability, drapability of two types of non-crimp fabrics (NCF, CCF300 45°/-45° and CCF300 0°/90°) and the mechanical properties of NCF reinforced composites are investigated in order to promote the further application of domestic carbon fiber and its NCF in liquid composites molding. The results show that the surface of the domestic CCF300 carbon fiber has high chemical and physical activity. And the NCF of CCF300 0°/90° shows good weaving quality. It is demonstrated that the NCF reinforced composites have the comparativemechanical properties with the unidirectional fabric reinforced composites. Thanks to the combination of good dimensional stability, drapability and formability, NCF has great potential to displace the traditional fabrics.

Key words: domestic CCF300 carbon fiber, surface property, NCF fabrics, deformation property, composites, mechanical property
