Abstract

The mechanical properties of palmyrah and talipot fibres have been evaluated. Like other natural fibres, these fibres were also found to be viscoelastic in nature. The variation of the initial modulus (YM), ultimate tensile strength (UTS) and elongation (%) values were determined as a function of fibre fineness, test length and speed of testing. Change in test length from 10 to 100 mm palmyrah fibres produces a decrease in UTS from 220 to 161 MN m−2. Such variations were not observed in the case of talipot fibres except at low test length. The observed results have been explained in the light of the structural characteristics of these fibres namely chemical constituents espiral angle, number of defect centres, cell sizes, etc.
