Experiment on the Quasi-Isotropy of Laminated Composite Plate

Abstract

The elastic properties of plate which was laminated in such a way as the elastic axes of consisting layer plates orient equingular, was proved to behave isotropic, theoretically. This paper shows Young's modulus of laminated composite plate made of a sort of layer plate, so that, the rubber coated fabric, 3 layered tire wall and 4 layered tire wall by experiment. From the result of the experiment, Young's modulus of the rubber coated fabric becomes constant and independent of the laminated orientation angle, but that of 3 layered tire wall and 4 layered tire wall become large at the direction of fiber.
