流化床粉未浸渍法中影响复合材料纤维含量因素的研究

STUDY ON FIBER CONTENT IN COMPOSITES PRODUCED WITH FINE POWDER DIPPING TECHNOLOGY BY FLUIDIZED BED

利用流化床技术,采用玻璃纤维或碳纤维浸渍PP或PA6树脂粉末,制备长纤维增强热塑性复合材料。采用正交设计的方法,研究浸渍工艺中静电压、气压和浸渍时间对纤维含量的影响。结果表明,增加浸渍时间、气压和静电压可提高复合材料中纤维含量,增强纤维的种类以及树脂粉末的种类与规格对复合材料中纤维的含量也有重要的影响。

With the fluidized bed technology, the continuous fiber reinforced thermoplastic plastics composites were prepared from glass fiber, carbon fiber, PP and PA6. The effects of electrostatic voltage, air pressure and dipping time of dipping technology on the fiber content were studied. The results show that the higher resin content can be gained by higher air pressure, electrostatic voltage and longer dipping time. The kind of reinforced fiber and the kind and size of resin affects the fiber content as well.
