COMPOSITE LAMINATED MATERIAL Russian patent published in 2002 - IPC

FIELD: production of composite laminated materials of structural designation changing the polydimensional shape of the article. SUBSTANCE: laminated material has an unbalanced structure relative to the selected axes of anisotropy, which at an external action produced a summary force or momentum vector differing from zero, or momentum vector relative to these axes causing a polydimensional deformation and reverts the material to the previous state after removal of the external action. The unbalanced structure is formed due asymmetry of orientation of layers or part of them at angles differing from the direction of the selected axis of anisotropy, due to arrangement of layers or layer packs at different distances from the plane passing through the middle of the material thickness, due to the use of heterogeneous or homogeneous materials having different properties. EFFECT: enhanced quality. 7 cl, 3 ex
