Composite material useful as actuator material, comprises a polymer, and a polycrystalline shape-memory material present in solid form exhibiting cavities, cracks and open pores, which are partially filled with the polymer

摘要

Composite material (a) comprises: at least one polycrystalline shape-memory material present in solid form exhibiting cavities, cracks (c) and open pores, which are formed during the production of the shape-memory material and/or by mechanical training and/or thermo-mechanical loading of the shape-memory material before its use; and at least one polymer (b). The cavities, cracks and open pores of the solid shape-memory material are at least partially filled with the polymer. An independent claim is also included for producing the composite material, comprising at least partially filling the cavities, cracks and open pores of the solid shape-memory material with at least one flowable polymer.
