Response of GFRP bars at different temperatures
Materials Research Proceedings, 2023Abstract. Owing to their numerous advantages, industries have been adopting fiber-reinforced polymer (FRP) bars as reinforcement in concrete members due to their superior mechanical properties and high durability. More specifically, glass FRP (GFRP) bars have been increasingly adopted for use in harsh environmental conditions due to their excellent ...

Experimental study on bond strength of GFRP bars
Materials Today: Proceedings, 2020Abstract Composite materials in the form of bars is good alternative to conventional steel due to their non corrosiveness. To work out effectiveness of GFRP bars as internal reinforcement in Civil Engineering structures, it is necessary to find its bond performance with concrete.

Curvilinear GFRP bars for tunnel segments applications
Composites Part B: Engineering, 2018Abstract The possibility of adopting glass-fiber reinforced polymer (GFRP) composite bars in tunnel segments as a substitute of the traditional steel reinforcement has been demonstrated. Nevertheless, this application requires a curvilinear shape for the reinforcement, and thus a different production process and rebar geometry.

Pultruded GFRP Reinforcing Bars with Carbon Nanotubes
2018Pultrusion is a renowned method in industry to produce glass fiber reinforced polymer (GFRP) reinforcing bars. Pristine multiwalled carbon nanotubes (P-MWCNTs) and multiwalled carbon nanotubes (MWCNTs) with carboxyl functional group (COOH-MWCNTs) were dispersed into the vinyl ester resin to produce GFRP bars.

Bond behaviour of GFRP bars in high-strength concrete: bar diameter effect
Magazine of Concrete Research, 2017The effects of reinforcing bar diameter and concrete compressive strength on the bond behaviour of glass fibre reinforced polymer (GFRP) bars were investigated. The primary experimental parameters were the type of reinforcing bar (steel, sand-coated GFRP and spiral-wrapped GFRP), the concrete compressive strength (20, 40 and 60 MPa) and the bar ...

Size effect on compressive behavior of GFRP bars
Challenge Journal of Structural MechanicsIn the last three decades, studies investigating the use of Glass Fiber Reinforced Polymer (GFRP) bars as an alternative to conventional steel rebars have increased due to their corrosive resistance. In addition to corrosion resistance, GFRP bars utilize high specific tensile strength, which makes them highly desirable in civil engineering applications.
