Core reilforced braided composite armour as a substitute to steel in concrete reinforcement

Abstract

This paper presents the work that is being done at the University of Minho concerning the development of brainded rods concrete reinforcement. Several samples of core reinforced braided fabrics have been produced varying the type of braided fabric (core reinforced and hybrid), the linear density of the core reinforcing yarns and the type of braiding structure (with or without ribs). The tensile properties of braided fabrics has also been analysed. Core reinforced braided composites rods were produced and tested to evaluate tensile and bending properties. The results obtained are presented and discussed. Reinforced concrete beams, with composite armour and steel armour, were produced and were subjected to bending test and the test results are presented. The adherence between composite rods and concrete was analysed as well.
