热塑性预浸带缠绕工艺参数及加热方式对成型质量及内应力的影响

INFLUENCE OF WINDING PARAMETERS AND OF HEATING SYSTEMS WITH THERMOPLASTIC TAPE ON QUALITIES AND INTERNAL STRESSES OF A PART

  • 摘要: 采用热塑性预浸料带APC-2/AS4 进行了热芯和火焰两种方法的缠绕研究, 分析了两种方法成型时预浸料带的温度2时间过程和两种方法下工艺参数对成型质量及内应力的影响。结果显示: 热芯缠绕时制件的厚度受芯模温度限制, 而火焰缠绕则不受限制。热芯缠绕时, 缠绕张力和预浸料带的树脂含量是影响制件质量的主要因素。

     

    Abstract: APC-2/AS4 prepreg tape winding with a heated mandrel and a flame was investigated. The temperaturetime processes of these two winding methods and the influence of winding parameters on qualities and internal stresses were also analyzed. The results show that the thickness of a part wound with a heated mandrel is limited by the highest temperature of mandrel and the thickness of that wound with a flame is unlimited. Tension and the matrix content of a tape are the most important parameters for a good quality part wound with a heated mandrel.
