New thermoplastic CFRP bendable rebars for reinforcing structural concrete elements
This paper presents test results for new thermoplastic carbon fiber-reinforced polymer (CFRP) bendable rebars to be used as reinforcement for concrete structures. The new CFRP rebar is made of carbon fibers bonded together with thermoplastic resin which allows bending of the rebar – by heating – several times after the complete solidification of the resin. A microscopic study was performed to optimize the magnitude of the pressure and heat required to manufacture and bend the CFRP rebar. Once the manufacturing parameters were determined, three tests were conducted to evaluate the rebars’ mechanical characteristics, namely: tensile strength test, pullout test, and bent bars and stirrups test. Based on the test results and modes of failure of the tested specimens, several possible modifications are proposed to improve the structure, and consequently the mechanical characteristics of the new thermoplastic CFRP rebars.
