| 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. |
