摘要:

针对现有展纤装置存在的问题,对纤维束展纤机理开展研究,在实验室机械展纤设备的基础上,将振动展纤与气流喷吹展纤相结合,搭建了振动喷吹展纤装置,建立了碳纤维展宽理论模型。并对展纤工艺参数进行了优化分析。结果表明,适当增大气流速度、振动幅度及振动频率有助于提升碳纤维展纤宽度与均匀性,与传统机械展纤工艺相比,能够保证较低的展纤断裂率,所设计的振动喷吹展纤装置可将12 k碳纤维束稳定展宽至17.6 mm,均匀度达到94.7 %,纤维断裂率降低至0.036 %。

Abstract:

Aiming at the problems existing in the spreading device, the fiber bundle spreading mechanism was investigated. Based on the laboratory mechanical spreading equipment, a vibration⁃blowing spreading device was constructed through a combination of vibration spreading and air⁃blowing spreading, and a theoretical model was established for carbon fiber spreading. The spreading process parameters were optimized. The investigation results indicated that with an increase in the airflow speed, the vibration amplitude and vibration frequency could help to improve the spreading width and uniformity of carbon fiber. This ensures a lower spreading fracture rate up to 0.036 % compared to the traditional mechanical spreading process.

Key words: vibration blowing fiber tow, carbon fiber, process parameter
