Abstract

The use of an apparatus which is able to fatigue test fibres in a new and original manner has revealed that a fatigue mechanism does exist in nylon fibres. This mechanism is revealed by a distinctive fracture morphology, as seen with the aid of a scanning electron microscope, and failure when the fibre is cycled to loads which, under steady conditions, would not result in fracture. It is shown that a necessary condition for fatigue failure is the cycling of the fibre to a zero minimum load. An explanation for the history and development of such a fatigue break is given.
