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毛细管流动的影响。本文首先将浸入边界法与相场法（IB - PFM）相结合，提出了一种新的数值方法。原始链网络（PCN）也用于固液界面的模拟。然后，利用微流控装置进行了流场可视化实验。柱状柱被放置在微通道中代表纤维。从孔隙形成的角度考察了纤维排列不均匀性和流速对孔隙形成的影响。
