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.
