大尺寸复合材料螺旋桨制造技术研究

Research on the manufacturing technology of large-size composite propeller

近几十年来,诸多国家都将目光投向了复合材料螺旋桨的设计与制造,复合材料螺旋桨的高强度、高阻尼、低密度特性为舰艇螺旋桨减振降噪设计提供了新的思路和途径。基于预浸料和半预浸料的真空袋压成型工艺,研发了舰船用大尺寸复合材料螺旋桨。真空袋压成型工艺制造效率高,成本低,解决了模具设计、工艺控制、成本控制等关键问题,为大尺寸复合材料螺旋桨的低成本快速制造积累了实践经验。

Many countries have focused their attention on the design and manufacturing of composite propellers in recent decades.The high strength,high damping and low density characteristics of composite propellers provide new ideas and ways for the design of ship propeller shock reduction and noise reduction.Large-size composite propellers were developed based on the vacuum bag pressing process of prepreg and semi-prepreg.This method with low cost and high efficiency solved key problems in manufacturing such as mold design,process control and cost control,and accumulated practical experience for the low-cost rapid manufacturing of large-size composite propellers.
