Abstract
High performance cementitious composites can be produced by reinforcement with a high volume of aligned fibers. One practical method of production of such composites would be based on the use of woven fabrics, where the bonding may be different from that predicted from evaluation of continuous aligned fibers. The present paper presents the study of the pull-out behavior of a fabric from a cementitious matrix. The influence of various fabric parameters were evaluated by comparing the pull-out of straight yarns (fibers), crimped yarns untied from the fabric and the fabric itself. The influence of initial tensioning of the yarns, which is an essential step in the production process, was also evaluated. SEM observations were carried out to interpret the pull-out curves in terms of microstructural characteristics. The crimped nature of the yarn was found to be an important factor in enhancing the bond of the fabric, as it generated anchoring effects. Tensioning of the yarn was detrimental to bond as it straightened the yarn and caused Poisson effects which damaged the interface.
