High modulus and ductile hybrid composite rebar

A new theoretical model of the hybrid composite rebar is proposed to counter the disadvantages such aslow elastic modulus , low elongation af ter break and high cost of current composite rebars. The glass compositerebars and hybrid composite rebars were fabricated. The single axial tensile behavior and accelerating corrosionproperties were tested and analyzed. The result s show that the tensile modulus of the new hybrid rebar is 142 GPa.Compared with the glass composite rebar , the new hybrid composite rebars possess the characteristics of corrosionresistance , good ductility and low cost .
