Multiaxial Tensile Testing of Textile Fabrics
The technical applications of the textile structures become more and more often and the measurement of their mechanical properties is very essential. The multiaxial testing of the textile fabrics is of special interest because the fabrics are non-isotropic materials. However the existing equipment is usually expensive and complex. In the present paper a new testing method is presented. The method is based on the operation of the corresponding testing equipment. The mechanical parts have been designed and constructed after their computational modelling so that the prediction and the exact estimation of their performance were possible. The design of the sensor and the electronic modules has been made exclusively designed in order to face the requirements of the measurements of the multiaxial tensile testing. The first version of the testing instrument gave promising results ensuring that the sensing principle is trustful and the mechanical and electronic parts are operational for the testing of knitted fabrics.
