Study on the Bending Fatigue Properties of Nomex Fiber

Abstract:

In this paper, we reported a bending fatigue testing apparatus which can test the bending fatigue properties of single Nomex fiber by setting the pretension, bending angle and temperature. The S-N and θ-N curves indicated that the pre-tension and bending angle had great influences on the bending fatigue life of Nomex fiber. A CCD camera was utilized to allow observation of the bending fatigue fracture morphology of fiber. It showed the fracture mechanism of Nomex fibers. The bending fatigue life of Nomex fiber was tested at different temperatures to show that its bending fatigue strength is strongly influenced by the temperature.
