Paper Abstract

By means of the off-axis collimated plane wave coherent light arrangement and a loading device by pure bending, Poisson's ratio values of CFRP ( carbon fiber-reinforced plactics plates, lay-up 0°, 90° ), GFRP ( glass fiber-reinforced plactics plates, radial direction ) and PMMA ( polymethyl methacrylate, x, y direction ) have been measured.

In virtue of this study, the ministry standard for Ministry of Aeronautical Industry ( Testing method for the measurement of Poisson's ratio of non-metallic by laser holographic interferometry ) had been published. The measurement process is fast and simple. The measuring results are reliable and accurate.
