ABSTRACT:
An aqueous composition for treating fibers for use in the resin transfer/injection molding of high density continuous fiber preforms which comprises about 0.005 to 0.05 php wetting agent, about 0.05 to 0.25 php binder, about 0.10 to 1.00 php polymer, about 0.005 to 0.05 php plasticizer and about 0.05 to 0.25 php water soluble oil, balance water, wherein the term "php" is intended to mean parts per 100 parts water (w/w). This composition, when applied to fibers, allows high fiber tension to be applied during preform fabrication without causing damage due to mechanical abrasion of the fibers. The composition also promotes resin to fiber adhesion and speeds the flow of resin through the dense preform during resin injection/transfer molding.
