Relaxation and creep behaviour of false banana’s fibre (Ensete ventricosum)

Popis výsledku v původním jazyce

This study was focused on the analysis of viscoelastic behaviour of fibres of false banana (Ensete ventricosum). The aim of the experiment was to describe the short term creep and relaxation behaviour under tension loading. The fibers of Ensete ventricosum, originally from Ethiopian region Hawasa, were used in this experiment. Moisture content Mc = 8.40 ± 0.67% (d. b.) and true density ?t = 668 ± 44 kg m-3 of the samples were determined. The specimens had initial gauge length of L0 = 100 ± 1 mm and the average yarn breaking load (YBL) after 20 tests was ?r = 14.3 ± 1.7 N. To determine the relationship between tension force and deformation, tension device (Labortech, MPTest 5.050, Czech Republic) was used to record the course of deformation function. All tests were performed using a constant rate ? = 3.1 N s-1. The short term creep tests were performed using constant loads of 30%, 60% and 90% of the average YBL. The short term relaxation tests were performed using constant strain of 30%, 60% and 90% o
