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.

Durability of GFRP Reinforcement Bars
2011Results of a 3-year-long investigation of durability of one type of glass fiber reinforced vinylester composite reinforcement bar are summarized. Bars were cast in concrete beams and subjected to simultaneous sustained load and exposure to one of four different environments: ambient indoor laboratory, natural outdoor weathering in central Pennsylvania,

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.

Tensile and Bond Properties of GFRP Reinforcing Bars
ACI Materials Journal, 1995The bond characteristics of four different types of glass fiber reinforced plastic (GFRP) reinforcing bars with different surface deformations were analyzed in experiments. Local bond stress-slip data, as well as bond stress-radial deformation data, needed for constitutive modeling of the interface mechanics, were obtained for varying levels of ...

Embedding Materials for Strengthening of Masonry with GFRP Bars
2003Un-reinforced masonry (URM) walls are one of the oldest and most widely used types of construction in the world but they are prone to failure when subjected to overstresses caused by out-of-plane and in-plane loads. The successful use of near surface mounted (NSM) fiber-reinforced polymer (FRP) bars for strengthening of concrete members has been ...
