抄録

A novel method is developed to determine the tensile strength of brittle fibers by means of a single-fiber fragmentation test. The parameters of Weibull distribution obtained from the fragmentation test can vary along with the variation of test condition because the difference of the test condition make the variation of stress recovery length where no fiber breaks can occur. The fragmentation tests with models of carbon fiber-reinforced vinylester and epoxy matrix composites are performed under some loading rates. Fragmentation test under Laser Raman Spectroscopy (LRS) is employed to measure the stress recovery length, and the parameters of Weibull distribution are derived from an analysis considering an effect of the stress recovery length. It is confirmed that the present method provides the constant fiber strength without reference to the difference of matrix and loading rate.
