Determination of the Elastic Constants of a Plain Woven Fabrics by Tensile Test in Various Directions

In this paper the values of elastic constants of woven fabrics for different angles of extension direction were analyzed. Four types of fabric samples of different raw material composition and the same type of weave were tested under tensile forces in seven directions oriented with 15° increment with respect to the weft direction. Elasticity modulus and Poisson's ratio of woven fabrics were determined experimentally in the laboratory. Based on the experimentally obtained values, theoretically calculated elastic constants for arbitrarily chosen fabric directions were calculated. A good agreement between experimental results and the calculated obtained values of the elastic constants was shown, so the theoretical equations can be used with high accuracy to calculate the elastic constants of the fabric in various directions. Therefore, the measurements need to be implemented when the tensile force acting on the fabric only in the warp, weft and at an angle of 45°.
