U.S. Patent application 15/663, 334.15/663, 334https://hdl.handle.net/2144/36932A bilayer composite thin-film beam structure is described. The structure incorporates a bulk phase change material as small inclusions in one layer of a bimorph. The structure, also referred to as a “phase change composite bimorph” or “PCBM”, curls abruptly, and reversibly, at a phase transition temperature. Large curling and effective expansion coefficients are demonstrated. The PCBMs may be employed in various self-assembly mechanisms and actuators.Preformed parts characterized by their structureShaping compositesAcrylic resin particlesLayered products comprising a layer of synthetic resinPhase change composite bimorphsPatent438192
