Abstract
The effect of commercially available S-2 glass sized fiber systems on the microscopic flow behavior of vinyl ester and epoxy systems was investigated. This was done by using a previously developed technique to monitor the effects of fiber-sizing-surface interactions on the flow of resin around fibers aligned in the direction of bulk flow. Surface energy effects were found to play an important role in determining microscopic flow behavior. It was found that surface free energies of the investigated fibers are significantly varied, and that the resulting differences in resin-fiber compatibility influence flow behavior. In particular a significant retardation in the flow of resin into fiber bundles was noticed for fiber-resin systems expected to possess lower capillary driving forces. The results indicate that fiber-sizing interactions will affect the rate of two impregnation and that the selection of a sizing-resin pair for RTM must take into account such considerations.
