    摘要： A method for making a preform includes creating a pressure differential between an inside and an outside of a perforated shape memory polymer mandrel in its temporary shape. The pressure differential is such that pressure outside the perforated shape memory polymer mandrel is greater than pressure inside the perforated shape memory polymer mandrel. The perforated shape memory polymer mandrel has i) a predetermined preform shape as the temporary shape and ii) a shrunken shape as its permanent shape, wherein the shrunken shape is configured such that it is removable from the predetermined preform shape. The method further includes depositing, as the pressure differential is maintained, at least one material onto a surface of the perforated shape memory polymer mandrel. The at least one material is set in the predetermined preform shape, thereby forming the preform.

    摘要： A composite item is fabricated in system that includes a layer of preform, supply of resin, mandrel, and bagging film. The layer of preform corresponds to the composite item. The supply of resin is sufficient to infuse the preform. The mandrel includes a preform receiving zone to receive the layer of preform and a resin receiving zone to receive the supply of resin. The resin receiving zone is adjacent to the preform receiving zone. The bagging film is operable to generate an envelope surrounding the preform receiving zone and the resin receiving zone.
