Abstract

Recently an attempt that directly applies GFRP plate to structural members is increasing. The researches for investigation of mechanical properties of GFRP plate have been progressed. KS(Korea Standard) M ISO 527(Determination of tensile properties of plastics) based on regulations of ACI 440.3R-04 and ASTM D 3039 is often used for GFRP plate tensile test. However, there is no specific standard for tensile test of GFRP plate. KS M ISO 527, when applied to GFRP plate, causes to sliding failure at the grip in case of rectangular specimen or causes local failure at tapered section of specimen that has dumbbell-shape. So, it is difficult to evaluate the tensile properties of GFRP plate exactly according any current standards. Therefore, this study proposes new standard methodology for tensile test of GFRP plate, through the tests which carried by KS M ISO 527, two methods with different grip and four proposed methods that have different grip and length.


According  to  experimental  results,  the  proposed  tensile  test  method,  which  extended  length  of  grip, attached specimen with epoxy and combined grip with hydraulic jack was more effective than existing tensile test method, such as the KS M ISO 527, ACI 440.3R-04 and ASTM D 3039, for applying GFRP plate.
