摘要：
One method of forming a part includes deforming a shape memory polymer from a permanent shape into a temporary shape, where the permanent shape of the shape memory polymer is a predetermined part shape and the temporary shape is a shape larger than the predetermined part shape. The shape memory polymer in each of the permanent shape and the temporary shape defines a cavity therein. The method further includes introducing a molding material into the cavity of the shape memory polymer, and reverting the shape memory polymer back into its permanent shape. Other methods for forming the part are also disclosed herein.
