摘要：

A new method of determination of the axial Poisson's ratio of single carbon fibres is presented. The proposed method, based on a laser diffractographic technique, provides measurements of the axial Poisson's ratio with an accuracy of 5.7%. Measurements on three types of carbon fibres demonstrates that the grand mean value of the axial Poisson's ratio takes values in the range 0.26-0.28. Moreover, analysis of changes in the fibre diameter with elongation, measured in nine different directions in the plane of a fibre cross-section, displays the anisotropic nature of the axial Poisson's ratio.
