Systems and methods are described where at least one roller (e.g., a kicker roller) is used to impregnate fibers (i.e., a charge or reinforcement) with a liquid resin (i.e., matrix) by eliminating air from the resin and fibers as they enter a pressurized zone. Air is forced out as the resin is first drawn into an entry zone of the roller, then into an entry gap adjacent to the roller, and then into the pressurized zone on the opposite side of the roller. The pressurized zone is an enclosed area at the output side of the roller where the resin is allowed to accumulate and the resin and composite combination are then forced out through a small exit gap. Shear forces between the surface of the quickly rotating driven roller and the resin provide the driving force. The fibers may be continuous (e.g., from a roller) or discontinuous or loose cut.
