Method and device for impregnating fiber bundles with resin

Resin impregnation of fiber bundles for use in making a composite material is described. The improvements of the disclosed method and impregnation head enable high fiber take-off speeds without excessive damage or fraying of the fiber bundles. Encapsulated air or voids in the impregnated product are consistently less than 1 % by volume of the impregnated product and decrease with increased take-off speed. These improvements are achieved by passing the fiber bunbles (40) through a multi-chambered impregnation head (10) in which the resin is injected into a downstream chamber (28). The cross-sectional area of the fiber bundles, the velocity of the fiber bundles, the size of the openings to the chamber, the viscosity of the resin and the pressure at which the resin is pumped into the downstream chamber all control the pressure within the downstream chamber.

The wall of resin minimizes the air that is encapsulated with the resin and prevents air from entering the downstream chamber. The pressures and counter flow of resin within the impregnation head drives encapsulated air out of the resin.
