Shear characterization of para-aramid (Twaron®) fabric by yarn pull-out method

The aim of this study was to determine the para-aramid fabric shear by the pull-out method. For this purpose, Twaron (R) type fabrics were used. The fabric width/length ratio and the number of pull-out ends were identified as important testing parameters. It was found that fabric shear depended on fabric density. Fabric shear strength increased when the number of pulled ends increased. When the fabric width/length ratio decreased, fabric shear strength increased. The number of pulled ends and the fabric width/length ratios influenced the fabric shear rigidity. Also, shear jamming angles were found to be based on the number of pulled ends. The results showed that para-aramid fabric shear could be measured by the yarn pull-out test.
