Abstract
An apparatus and method for pultruding reinforced plastic articles. The apparatus includes a first, hot die having a long tapered portion. The hot die partially consolidates resin-impregnated fibers into an oversized form. After exiting the hot die, the partially consolidated material is passed through a second, cooling die which finally consolidates the material and forms it into the desired, final shape. The cooling die is at a temperature less than the temperature of the hot die. Preferably, the cooling die has a tapered portion which is shorter than the tapered portion of the first die. A method is disclosed for pultruding plastic articles using the apparatus.
