Mechanical and durability properties of GFRP bars exposed to aggressive solution environments

Science and Engineering of Composite Materials, 2021
Two categories of GFRP specimens, in nominal diameters of 11.2 mm and 15.6 mm respectively, made of E-glass fibers and a vinylester resin were immersed in alkaline solution, saline solution and tap water solution at room temperature.

An Experimental Study on Effect of Concrete Type on Bond Strength of GFRP Bars [PDF]

Journal of Rehabilitation in Civil Engineering, 2021
One of the common methods to create bond strength in reinforced concrete is providing development length. The bond strength of glass fiber reinforced polymer (GFRP) bar is inherently poor due to its shape, as well as its inadequate mechanical ...

Infrared laser heating of GFRP bars and finite element temperature field simulation

Journal of Materials Research and Technology, 2022
Glass fiber-reinforced polymer (GFRP) composites were prepared with ortho-phthalic unsaturated polyester resin as the matrix. Mass productions were carried out on a production line using infrared laser radiation and tunnel-kiln heating.
