Cylinder tester which can apply circumferencial stress, axial stress and torsional moment simultaneously using cylinder-shaped coated fabric specimen was made by the authors. The torsional angle-torsional moment responses of three kinds of coated plain weave fabric subjected to small circumferencial and axial stress were studied. The torsional response of the material was approximately linear. Assuming the specimen was a cylindrically elastic material, a simple expression for practical calculation of shear elastic coefficient was obtained. The coefficient of respective specimens was calculated using the expression. The shear coefficient of PTFE coated material was about six times of that of PVC coated material.
