Abstract

The stress-strain curve for banana fibre i s determined. Properties such as the initial13; modulus (YM), ultimate tensile strength (UTS) and percentage elongation are evaluated as13; a function of fibre diameter, test length and speed of testing. It is found that YM, UTS13; and % elongation show l i t t l e variation in their values for fibres of diameter ranging from13; 50 to 250pm. The UTS and breaking strain are found to decrease with an increase in the13; test length while both breaking strength and breaking strain remain constant with the13; increase of speed of testing from 0.5 to 100 x m and after they both decrease. These observed properties are explained on the basis of the internal structure of the fibre, namely, the number of cells, spiral angle and the number of defects. Scanning electron microscopic (SEM) studies of the fractured surfaces of these fibres indiacte that the failure is due to pull-out of microfibrils panied by tearing of cell walls; the tendency for fibre pull-out seems to decrease with increasing speed of testing.
