Abstract

In this study, resin permeability of plain-woven composites is analyzed using a three-scale homogenization method. To this end, the three-scale homogenization method is developed to analyze the resin flow through both the structures of fiber bundles and the inside of fiber bundles, and also the mesoscopic and macroscopic resin permeability. To evaluate the validity of this method, resin permeability and characteristic flow velocity of plain-woven glass fiber-reinforced plastic (GFRP) are analyzed. The results show that the present method successfully analyzes the resin permeability of plain-woven composites.
