摘要： The disclosure is directed to a process for producing resin infused composite parts having improved structural performance and improved surface appearance. The process comprises the steps of positioning a dry composite preform on a forming tool component, arranging resin exit lines in close proximity to the perform, placing a permeable release material on the perform, and placing a first piece of flow media over the release material. 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.

摘要： The invention is directed to a process for elimination of deformations on resin infused composite parts in which the resin distribution tube used in a resin vacuum infusion process is positioned above the surface of a preform and is not in contact with the preform. Flow media indirectly connects the resin distribution tube to the preform which allows for free movement of resin without direct contact of the resin distribution tube to the perform, and thus, this eliminates deformations that are caused by direct contact of the resin distribution tube to the preform.
