This paper describes the work that is being done at the University of Minho concerningthe development of braided rods for concrete reinforcement. A preliminary research study has beenconducted to understand the mechanical behaviour of braided fabrics. Various samples have beenproduced varying the type of fiber (glass, polyester and aramid), the type of braided fabric (simple,hybrid and core reinforced) and in the latter case, the number of core reinforcing yarns. The tensileproperties of these samples have been evaluated and the results presented. The influence of eachfactor on the tensile properties of braided fabrics has also been analysed and discussed. In order toproduce braided reinforced composite rods to use as a concrete reinforcement, a special techniquehas been developed using a standard vertical braiding machine. The braided reinforced compositematerials have been produced in rib structure to improve adhesion between them and the concrete.Special samples have been prepared and tested to evaluate the adherence between both materialsinvolved. The tensile and bending properties of braided reinforced composite rods have beenevaluated and the results obtained presented and discussed
