Abstract: This paper describes and analyzes experimental methods of obtaining in-plane shear modulus for rubber-steel cord composites. In view of the special characteristics of the composites, many approaches to determining experimentally shear modulus of a general composite are not suitable. The author strongly recommends that 45° off-axial tension of a double layered 0°/90° layup is to be conducted so as to facilitate tests and assure accuracy of the measurements. Besides, it is worth noting that the clamped ends induce twist for the double layer structure because the specimen's thickness is generally larger than that of other composites. To get rid of the bad effect, a test machine with ratable grip system is to be employed.
Key words: rubber-cord, shear modulus- off-axial tension
