Abstract
An apparatus and method for the production of molding compositions for fiber-reinforced resin composites in which chopped fiber tow is fluidized, expanded and admixed with dry powdered resin is disclosed. Fluidized fibers are conveyed through a flow accelerating device and discharged into an enlarged mixing chamber wherein turbulent admixing with powdered resin injected therein occurs.
