  • Apparatus for fiber impregnation
    Patent number: 5766357
    Abstract: An apparatus for fiber impregnation for use in a fiber placement system is disclosed. Resin is impregnated in the fiber rovings as they pass through a manifold. The manifold includes grooves for the fibers to travel, a reservoir to receive the resin and channels for the resin to flow to the individual fibers for impregnation. A control system measures and monitors the fiber speed and then mixes, pumps and delivers the desired quantity of resin to the tows for impregnation.
