Abstract: A method and apparatus for fabricating a composite part, such as a fuselage or internal stiffener, with a shape memory polymer (SMP) apparatus usable as a rigid lay-up tool. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. For example, cavities may be formed into the SMP apparatus for nesting components therein to co-bond or co-cure with the composite part. The composite material and/or nested components may be heated and compressed against the SMP apparatus. The SMP apparatus may be configured to remain rigid during the composite cure cycle. Once the composite material is cured, the SMP apparatus may be triggered to a malleable state and urged away from the cured composite material.

Abstract: 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.

Abstract: A method and apparatus for fabricating a composite part with a shape memory polymer (SMP) apparatus usable as both a rigid lay-up tool and as a bladder. The SMP apparatus may be heated until malleable, shaped, and then cooled in a desired rigid tool configuration. For example, cavities may be formed into the SMP apparatus for nesting components therein to co-bond or co-cure with the composite part. The composite material may be applied onto the SMP apparatus in the rigid tool configuration and then placed into a rigid external tool and heated to composite cure temperatures at which the SMP apparatus is malleable. A pressure differential may be induced which urges the SMP apparatus to compress the composite material against the rigid external tool. When the composite material is cured, the SMP apparatus may be urged away from the cure composite material and removed from within the composite part.

Abstract: A method and apparatus for removing a SMP apparatus from within a cured composite part. The method may comprise the steps of triggering the SMP apparatus from a rigid state to a malleable state, inducing a pressure differential that drives the SMP apparatus, in the malleable state, away from the cured composite part and toward an inner mandrel tool, and removing the inner mandrel tool with the SMP apparatus resting thereon out of the cured composite part. The inner mandrel tool may comprise an outer surface having varying contours such that a surface area of the outer surface is great enough to prevent the SMP apparatus from folding over onto itself or creasing when driven toward the inner mandrel tool. A maximum straight line distance between points on the outer surface may be small enough to allow the inner mandrel tool clearance for removal from the cured composite part.
