Abstract

Abstract: Based on the experimental study, the influence of fiber volume fraction and fiber length on the tensile strength and tensile strain of BFRC are discussed. And the tensile failure mode of BFRC is analyzed. The results show that the fiber volume fraction can significantly improve the tensile strength of BFRC. The tensile strain of BFRC is obviously enhanced by fiber length. The fracture surface roughness coefficient of BFRC decreases in power function with the increase of fiber volume fraction. And the roughness coefficient can be used as the evaluation index of FRC tensile properties.
