METHOD FOR PREPARING PREFORMS FOR MOLDING PROCESSES

摘要

Preforms for molding processes are prepared by applying an aqueous dispersion of a tackifier onto one or more reinforcement fibers, (2) drying the coated reinforcement fibers to remove the water present and (3) forming one or more of the coated reinforcement fibers into a predetermined shape. The preforms comprise reinforcement fibers having a substantially uniformly distributed tackifier on the surface thereof in the form of a discontinuous film coating.
