摘要： A system and method for forming a hollow, complex, monolithic composite part. Composite material may be placed around the mandrel, then an internal impermeable membrane may be placed into and/or through tunnels formed in the mandrel. Next, an external impermeable membrane may be placed around the composite material and sealed against itself and the internal impermeable membrane such that the mandrel and the composite material are both contained in an airtight manner between the internal and external impermeable membranes. Air may then be removed from within the sealed impermeable membranes, compressing the impermeable membranes against the mandrel and/or the composite material. The consolidated composite material may be hardened to form the composite part. Finally, the impermeable membrane may be removed from around the hollow composite part and from within the mandrel, followed by removal of the mandrel from within the composite part by breaking it up into smaller pieces.

摘要： A method and support apparatus for providing structural support to a mold or mandrel, such as a shape memory polymer (SMP) apparatus configured for shaping a composite part. The support apparatus may comprise a rigid structural member and a plurality of SMP cells attached thereto and configured to inflate or deploy in a malleable state toward and against a surface of the SMP apparatus, mold, or mandrel. Then the SMP cells may be returned to a rigid state while still pressed against this surface, thereby providing structural support when composite material is applied to an opposite surface of the SMP apparatus, mold, or mandrel. After the composite material is cured into the finished composite part, the SMP cells may be deflated or otherwise collapse toward the structural member to provide enough clearance to be removed from the cured composite part.

摘要： A mandrel used with forming composite parts includes an outer surface on which composite material is placed, and a groove in which splice material is filled. The groove may be positioned on the outer surface along the length of the mandrel. A method for forming composite parts includes the steps of providing a mandrel that includes a groove aligned with its longitudinal axis, filling the groove with splice material, cutting the composite material to match the shape and the size of the mandrel, placing the composite material around the outer surface of the mandrel, and curing the composite material and the mandrel.
