| Outline of Final Research Achievements |
Prediction of a resin impregnation behavior is technically important in fiber reinforced plastics (FRP) as a structural material. Permeability, which is a parameter of an easiness of impregnation, is evaluated by the Darcy’s Law. Now, the only way to evaluate permeability is empirical methods, in which resin is flown into reinforcements. Thus, individual measurement is necessary if a material system was changed. In this study, we focused on the correlation between permeability and wettability of material system. Microscopic resin impregnation behavior was improved with increasing of wettability, and it showed inverse correlation with apparent permeability. Therefore, we evaluated the resin impregnation behavior in different scales, which were inside and circumference of fiber bundles. We found that the microscopic permeability inside fiber bundle was predominant rather than the macroscopic permeability measured with reinforcement fabric.
