Impregnation and in-plane resin flow of film-stacking material under compression process were investigated. The understanding of this phenomenon is the key to optimize the impregnation process under pressure rollers in a double-belt press for organo-sheet production. The stack of carbon fiber woven fabrics and viscous fluid were compressed in a flat open-edge mold under various controlled conditions using a testing machine. The impregnation, in-plane flow, and pressure profile were characterized from the experimental observations. Furthermore, a theoretical model was developed to describe the impregnation and in-plane flow behavior. The model prediction showed decent agreement with the experimental data. The developed model will be useful to optimize the process parameters of double belt press process.

研究了成膜材料在压缩过程中的浸渍和面内树脂流动。对这种现象的理解是优化用于有机板生产的双带压力机中压力辊下浸渍工艺的关键。使用测试机，在各种受控条件下，将一叠碳纤维机织织物和粘性流体在一个扁平的敞口式模具中进行压缩。从实验观察中表征了浸渍，平面内流动和压力分布。此外，开发了一个理论模型来描述浸渍和面内流动行为。模型预测结果与实验数据吻合良好。开发的模型将有助于优化双带压榨工艺的工艺参数。
