ABSTRACT:
A method of fabricating and using a removable, inflatable mandrel of shape memory polymer for use in manufacturing composite parts including the steps of providing a processed pre-form of shape memory polymer, replicating a mold with the shape memory polymer, using the mold as a mandrel in the creation of composite parts, and removing the shape memory mandrel quickly and easily from the part without damage to the finished part.
