Abstract
Apparatusfor forming a composite component is disclosed, the apparatus comprising: a deformable mold toolthat at least partially defines a mold cavity; an interface layerformed on an external surface of the mold tool; and at least two peristaltic actuators, mounted to contact the interface layerand to generate a peristaltic pressure wave in the mold tool. The peristaltic actuators comprise rollers, pistonsor bi-metallic blocks. A method of forming a composite component is also disclosed, the method employing a mold toolthat at least partially defines a mold cavity. The method comprises: placing reinforcing fibers into the mold cavity, forcing a matrix material into the mold cavitythrough the reinforcing fibers, and generating a peristaltic pressure wave within the mold toolduring forcing of the matrix material into the mold cavity
