The material (10) has layer composition with two layers. The layers include partial structures with direction orientations deviating from each other. The composite material is suitable to receive two different end forms. The composite material includes an actuator (12), with whose excitation the material changes from one of the stable forms into another stable form that is different from the former form. An independent claim is also included for an assembly e.g. car body assembly, for a motor vehicle. Die vorliegende Erfindung betrifft ein Verbundmaterial (10) mit einem Schichtaufbau, umfassend mindestens zwei Schichten, wobei mindestens zwei Schichten des Verbundmaterials mindestens teilweise Strukturen mit voneinander abweichender Richtungsorientierung umfassen, wodurch das Verbundmaterial geeignet ist, mindestens zwei unterschiedliche Endformen einzunehmen, und wobei das Verbundmaterial weiterhin mindestens einen Aktuator (12) umfasst, bei dessen Anregung das Verbundmaterial von einer ersten stabilen Endform in eine zweite von dieser verschiedene stabile Endform übergeht.
