【摘要】 熔融浸渍工艺制备连续纤维增强PEEK预浸带 ,要求纤维束必须预分散以获得浸渍效果较好的预浸带。本文利用纤维分散装置使纤维分散 ,发现纤维束的总包覆角为 2 70°、纤维张力为 2 5N时 ,纤维可被较好地分散 ;过高的总包覆角和纤维张力容易使纤维磨损程度加剧。更多还原

【Abstract】 In the process of producing continuous fiber reinforced PEEK prepreg with the melt impregnation method, the fiber bundles are required to be well pre-dispersed to acquire good impregnated prepreg. In this paper, fiber bundles were dispersed by the special fiber dispersion device.The fibre bundles could be well dispersed while the total wrap angle is 270°and fiber tension around 25N. But when the total wrap angle and fiber tension is bigger, fiber will be damaged severely.更多还原
