| Abstract: | The morphological, physical, and mechanical properties of the nonwood plant fiber bundles of ramie, pineapple, sansevieria,
kenaf, abaca, sisal, and coconut fiber bundles were investigated. All fibers except those of coconut fiber had noncircular
cross-sectional shapes. The crosssectional area of the fiber bundles was evaluated by an improved method using scanning electron
microscope images. The coefficient factor defined as the ratio of the cross-sectional area determined by diameter measurement,
to the cross-sectional area determined by image analysis was between 0.92 and 0.96 for all fibers. This indicated that the
area determined by diameter measurement was available. The densities of the fiber bundles decreased with increasing diameters.
The diameters of each fiber species had small variation of around 3.4%-9.8% within a specimen. The tensile strength and Young’s
modulus of ramie, pineapple, and sansevieria fiber bundles showed excellent values in comparison with the other fibers. The
tensile strength and Young’s modulus showed a decreasing trend with increasing diameter of fiber bundles. |
