Abstract: front page image
(EN)A multilayered composite shape memory material includes a coextruded first polymer layer of a first polymer material and a second polymer layer of a second polymer material. The composite shape memory material after thermomechanical programming being capable of undergoing at least one temperature induced shape transition from a temporary shape to a permanent shape. The first polymer layer defines a hard segment of the shape memory material that provides the shape memory material with the permanent shape, and the second polymer layer defines a switching segment of the shape memory material that provides the shape memory material with the temporary shape.
(FR)L'invention concerne un matériau multicouche composite à mémoire de forme comprenant une première couche polymère coextrudée d'un premier matériau polymère et une seconde couche polymère d'un second matériau polymère. Le matériau composite à mémoire de forme, après programmation thermomécanique, peut subir au moins une transition de forme induite par la température et passer d'une forme temporaire à une forme permanente. La première couche polymère constitue un segment dur du matériau à mémoire de forme, ce qui confère à ce dernier sa forme permanente, et la seconde couche polymère constitue un segment de mutation du matériau à mémoire de forme, ce qui confère à celui-ci sa forme temporaire.
