Abstract:
1. A process for producing resin infused composite parts having improved structural performance and improved surface appearance, the process comprising the steps of: positioning a dry composite preform on a forming tool component; arranging resin exit lines in close proximity to the preform; placing a permeable release material on the preform; placing a first piece of flow media over the release material; 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, such that the resin distribution tube is not in contact with the bagged preform.
