| 摘 要： | 利用热压工艺制备了三种不同等温结晶时间的连续碳纤维（CF）增强尼龙6（PA6）单向复合材料，并分别研究了吸湿前后连续CF/PA6复合材料单向板的0°拉伸、90°拉伸、弯曲和层间剪切性能变化。结果发现，CF/PA6复合材料的0°拉伸、90°拉伸、弯曲和层间剪切强度（模量）分别下降了10%~37%（0~0.6%）、35%~46%（62%~64%）、53%~61%（16%~28%）和5%~31%。结合SEM断面观察和抛光金相显微学给出了吸湿对CF/PA6复合材料性能的影响机制。

| Abstract: | Continuous carbon fiber reinforced polyamide 6 (CF/PA6) unidirectional laminates with three different isothermal crystallization time were prepared. The tensile tests of 0° and 90°, the bending and interlaminar shear tests before and after water absorption of CF/PA6 composites were then respectively performed. The results show that the strength (and modulus) of 0° and 90° tensile, bending and interlaminar shear of CF/PA6 composites are decreased by 10%-37% (0-0.6%), 35%-46% (62%-64%), 53%-61% (16%-28%) and 5%-31%, respectively. The effect mechanism of water absorption on the properties of CF/PA6 composite is given with the help of further characterization methods of SEM and metallographic microscopy. |
