Flexural rigidity of a porous resin/Al laminate is estimated experimentally by means of the 3-points bending test. It can be seen from the results that the change in the magnitude of flexural rigidity of the laminate is convex with respect to its forming magnification. Therefore there exists the optimal value of the forming magnification of porous resin for the frexial rigidity. The neutral band in which the bending stress is free around the neutral plane of the porous resin/Al laminate beam is devised and the neutral band model is used for the calculation of the frexural rigidity of the laminate beam. The results obtained are good agreement with the experimental ones of the convex change in flexural rigidity with the forming magnification.
