Low pressure vacuum resin infusion system

摘要

A mold assembly includes a support table mounted for rotation within a vacuum chamber. A plurality of hollow part molds is radially disposed about an axis of rotation of the support table. Each part mold has fiber architecture disposed between an inflatable bladder and internal walls of the part mold. A first motor rotates the support table and resin is urged by centrifugal force to flow along the length of each part mold until the fiber architecture is thoroughly impregnated with resin. A second motor spins each part mold about an axis of rotation of the part mold to ensure that the resin migrates radially outwardly relative to the interior wall surface of each part mold. The resulting product is a monolithic, seamless part having no voids.
