A multi-station apparatus for fatiguing fibres in various environments

The paper describes a new multi-station apparatus for fatigue testing textile fibres by the technique of biaxial rotation over a pin. This involves the tension-compression of fibres which are rotated whilst bent around a pin. Ten fibres may be tested simultaneously in both gaseous and liquid environments and some initial results are presented. The tester features an inexpensive electronic control system based around a single board microcomputer and is readily adaptable to meet the changing and expanding needs of the user.
