ABSTRACT:
This invention is a method and apparatus for wetting fiber reinforcements with plastic or resin matrix materials. The fibers are impregnated with matrix material, associated into a tow, passed through a pultrusion die and degassed by applying a reduced pressure. The apparatus includes a pultrusion die having an elongated body having a longitudinally extending channel through which the tow is pulled, entrance and exit ports, a first, enlarged diameter cavity portion, at least one matrix material injection port for injecting matrix material under pressure into the first cavity and into the tow, and a second enlarged cavity portion having a low pressure application port for applying a pressure substantially below that of the first cavity. The apparatus may alternatively have only one enlarged cavity portion, with both injection and vacuum application ports, or alternatively, may be used with conventional wet bath equipment, where an enlarged cavity portion is used for vacuum application.
