Abstract
In this study, the interaction between resin and fiber was simulated based on the coarse grained molecular dynamics with a model of resin and fibers with various surface structures. The main target of this simulation is to evaluate the effect of surface structures on the contact angle between resin and fiber. In the result, there was a tendency to be small the contact angle between fiber and resin when a simulated silane coupling treatment was applied on the surface of a fiber model. Therefore coarse-grained molecular simulation shows the same trend as the contact angle measurement test, suggesting that it is possible to evaluate the change in wettability by surface modification. on the coarse grained molecular dynamics.
