ABSTRACT
The fatigue and durability of monofilament fishing gut and multifilament fishing gut were compared in fatigue tests employing repeated elongation under a load and flection. The fatigue life of both types of gut was shorter in the case of flection than elongation.
Also, in terms of elongation, the monofilament fishing gut exhibited greater durability than the multifilament type. In the case of multifilament fishing gut, a great reduction in strength was observed as the fatigue progressed. In the case of the monofilament fishing gut, no reduction in strength was observed at all. These results suggest that the fatigue mechanism of the two types of fishing gut is different and that the twist and the existence of interaction between the filaments exert an influence on the fatigue characteristics of multifilament fishing gut.
