Microscale resin impregnation was investigated for capillary flow inside tows of composite materials. We first developed a novel numerical method by combining Immersed Boundary Method and Phase-Field Method (IB - PFM). Primitive Chain Network (PCN) simulation was also used in solid-liquid interface. Then, flow visualization experiments were carried out using a microfluidic-device. Columnar pillars were placed in microchannels torepresent fibers. The influences of irregularity of fiber arrangement and flow velocity were investigated from the view point of void formation.

研究了微尺度树脂浸渍对复合材料丝束内毛细管流动的影响。我们首次将浸没边界方法和相场方法相结合，提出了一种新的数值方法。固液界面也采用了原始链网络(PCN)模拟。然后，利用微流控装置进行了流动可视化实验。柱状柱被放置在微通道中以代表纤维。从空穴形成的角度研究了纤维排列的不规则性和流动速度的影响。
