Process of producing preforms containing light weight filler particles |
摘要 |
A method and apparatus of producing and using composite fibers in a liquid molding process. The composite fibers are formed from a base material and filler particles which are lighter or less expensive than the base material. A preform screen is placed at the bottom of a tank. The tank is filled with liquid, the composite fibers and a mass of reinforcing fibers creating a slurry above the screen. The screen is raised up through the slurry causing the composite fibers and the reinforcing fibers to be deposited on the screen creating a fiber preform. The preform is then removed from the screen and is placed in a mold for use in a liquid molding process.
