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.

研究了微型树脂浸渍复合材料丝束内部毛细管流动的情况。我们首先结合浸入边界法和相场法（IB - PFM）开发了一种新颖的数值方法。原链网络（PCN）模拟也被用于固液界面。然后，使用微流体装置进行流动可视化实验。将柱状柱放置在微通道中以代表纤维。从空隙形成的角度研究了纤维排列不规则性和流速的影响。
