TEARING PROPERTIES OF COATED MULTI-AXIAL WARP KNITTED FABRIC

Abstract In this paper, the tearing properties of a multi-axial warp knitted fabric produced with glass filaments and coated with PVC resin are presented. The typical tearing load-extension curves and influences of the different tearing testing conditions are analyzed. The results show that the tearing properties of the coated multi-axial warp fabric are different from those of the coated woven fabrics and that they depend on the tearing directions and tearing methods. The trapezoidal method and tearing tests along diagonal directions give higher resistance against tearing propagation.
