NEW APPROACH TO TENSILE STRENGTH TESTING OF CEMENT-BASED FRP COMPOSITE WRAPPED SPECIMENS

A novel technique for evaluating the tensile strength of FRP tow sheets and cement-based specimens wrapped with FRP tow sheet composites is introduced. The ASCERA hydraulic tensile tester is used for determining the tensile strength which is derived from the hydraulic pressure and sample geometry. The tensile strength of the carbon fiber wrapped cement composites were in the range of 78 to 132 MPa. The glass fiber composites were in the range of 40 to 55 MPa, while the unwrapped cement specimens were under 7 MPa. The results show a significant difference in tensile strength properties with the application of epoxy-resin system. The tensile strength values are presented using Weibull statistics. A model using the rule of mixtures is used to predict the tensile strength of the FRP composites. Fractography is used to locate the failure initiating defects and to identify the failure modes associated with the different composite wrap systems.
