Characterization of the tool-part interaction during the curing of CFRP composites

  • 摘要: 利用光纤Bragg(布拉格)光栅(fiber Bragg grating, FBG)传感器,结合理论模型,对碳纤维复合材料(CFRP)热压罐成形过程中模具构件间的作用力进行了研究.结果表明,在模具表面涂覆脱模腊的条件下,模具与构件界面间不仅存在滑动摩擦力,还会发生粘接作用.固化完成后,温度下降使模具与构件产生不同程度的变形,导致粘接力上升,达到极限值时发生脱粘现象.脱粘首先发生在边缘,沿模具长度方向向中心移动.模具与构件热膨胀系数的差异是摩擦力产生和构件发生变形的主要原因.
