A rigid SMP bladder is molded into near-net shape and mold released.
Lay-up
The rigid SMP bladder is first used as a mandrel for composite lay-up.
Cure Prep
The composite lay-up on the SMP bladder is inserted into a clamshell mold.
Cure
The composite part is cured above the bladder's transition temperature. Pressure is applied to the bladder, inflating it against the interior of the composite.
Extract
When fully cured, the flexible SMP bladder is depressurized and contracts for easy removal.
