ABSTRACT:
A method and apparatus for making fiber reinforced plastic preforms via a wet slurry process. A screen with the desired preform configuration is placed in the bottom of a tank. The tank is then filled with water and chopped fibers to create a slurry. The screen is raised up through the slurry causing fibers to be deposited on the screen in the shape of the preform. The preform is then removed from the screen, placed in a mold and injected with resin to form the desired structure.
