Abstract: The objective of this study was to explore the influences of different characteristics of warp knitted fabrics made from multifilament yarns on the tensile properties of TRC elements and the bonding developed between the fabrics and the cement matrix. Several parameters such as loop size, bundle size (number of filaments), and fiber type (different raw materials: High Density Polyethylene, Polypropylene, AR glass and Aramid) were examined. All the composite elements were produced by the pultrusion technique. It was found that the loop size of the fabric as well as the bundle diameter significantly influence the performance of the cement composite. Fabrics made from small bundle diameter and large loop size exhibited the highest efficiency factor and developed the best bond strengths with the cement matrix. This was explained based on tighten effects induced by the stitches of the fabric and cement penetrability in between the filaments of the bundle.
