The process further comprises the steps of wrapping a resin distribution tube with a second piece of flow media, placing a vacuum bag layer over the forming tool component, preform, release material, first and second pieces of flow media and resin distribution tube, such that the resin distribution tube is retained in a pleat formed in the vacuum bag layer and such that a bagged preform is formed, and positioning the resin distribution tube above the bagged preform.
