The authors proposed a shape controllable structural laminated material and its control method in the previous report. The material was composed of Aluminum alloy, CFRP and KFRP sheets and they were laminated unsymmetrically. In that report, the size of the laminated material as an object was only 100mm×100mm square. This report examined whether the application of this theory was possible on the more general sizes of ±45° angle ply unsymmetric laminate. Many experiments have proven the theoretical result. Main results obtained were as follows; (1) the theoretical prediction of thermal deformation by Joule heating on various dimension of the plates agreed well with measured value. (2) Torsion rate Kxy converged on the constant value, when aspect ratio exceeded one. (3) Torsion rate Kxy showed the maximum value in proportion to the total thickness of the laminates. (4) The effects of the dimensions on the deformation of the laminates were remarkable in the low temperature.
