Abstract
In this paper, statistical distribution of tensile strength of poly-p-phenylene benzobisoxazole (PBO) fiber with kinking damage was investigated in monofilament tests. Kinking damages was created on surface of virgin fiber by winding bundle fibers to steel rod. Diameter of steel rod was set to 5, 2.5, 1.25 and 0.65 mm. Kinking damage density was defined to evaluate occurrence of kinking damage. It was found that the tensile strength of fiber with kinking damage decreased with increasing kinking damage density. The tensile strength of fiber with kinking damage was well fitted the Weibull distribution function with 2 parameters. Tensile strength of PBO fiber with kinking damage was explained by concept of effective volume.
