An Experimental Study on the Tensile Properties of GFRP Rebar Produced by RTM (Resin Transfer Molding) Process

RTM 공정에 의해 생산된 GFRP 보강근의 인장특성에 관한 실험적 연구

The tensile properties of GFRP(glass fiber reinforced polymer) rods with various surface deformation produced by RTM(resin transfer molding) process were analyzes experimentally. Two types of GFRP rods with different surface deformation manufactured by RTM process in domestic area and two types of GFRP rods imported were considered in this study. All testing procedures including specimens preparation, set-up of test equipments and measuring devices were made according to the ASTM D3916-02 recommendations. From the test results, it was found that wave-type GFRP rod made by RTM process showed the highest tensile strength due to the highest fiber volume ratio.
