Abstract

The fatigue fracture morphology of two nylon filaments (mono and 3-ply) have been inves-tigated.<br> Photographs of tensile fracture indicate that the two nylons show a similar straight fracture across the fiber axis. However, in fatigue fracture morphology, two typical kinds of morpho-logical feature are obtained.<br> In monofilament, fatigue fracture is developed along the fiber axis, showing longitudinal splitting (long tail-like rupture end). While in 3-ply filament, the fracture occurs across its axis, showing a plain rupture end.<br> It is suggested that the two types of fracture morphology reflect the different fracture mechanism between the two nylons.<br> These causes are discussed in detail in order to understand the fatigue mechanism of the nylon filaments.
