METHODS AND SYSTEMS FOR MANUFACTURING COMPOSITE PARTS WITH FEMALE TOOLS

A method for manufacturing a fiber-reinforced resin part comprises: positioning a plurality of fibers on a mold surface (204) of a tool (202); covering the fibers with a sealing layer (220); pressing a portion of the covered fibers against an interior transition region (206a, 206b) of the mold surfa...

Zusammenfassung:	A method for manufacturing a fiber-reinforced resin part comprises: positioning a plurality of fibers on a mold surface (204) of a tool (202); covering the fibers with a sealing layer (220); pressing a portion of the covered fibers against an interior transition region (206a, 206b) of the mold surface with a pressing device (234a, 234b); and while pressing the portion of covered fibers against the interior transition region, removing air from between the sealing layer and the mold surface to draw at least a partial vacuum between the sealing layer and the mold surface. A system for manufacturing a fiber-reinforced resin part comprises: means for positioning a plurality of fibers in the shape of the fiber-reinforced resin part; means for covering the plurality of fibers with a sealing layer; means, separate from the means for covering, for pressing a portion of the plurality of fibers against an interior transition region of the means for positioning; and means for drawing at least a partial vacuum between the means for covering and the means for positioning while pressing the portion of fibers against the interior transition region.
