Abstract
A method of manufacturing a composite structure, e.g. wind turbine blade, using reusable and removable perimeter plates to establish air flow channels in conjunction with a vacuum bag and mold. An exemplary setting is the perimeter of large wind blade shells where a perimeter vacuum is used to retain the part in the mold for the bonding process. The reusable plates disclosed herein create air channels whether the vacuum is introduced to the perimeter of the mold: i) through the flange in different locations; or ii) with the use of vacuum lines into the perimeter bag; or iii) built in vacuum channels in the flange of the mold.
