“…The shape anisotropy of B. mori fiber has a range of 1.1-1.5. Selivanova et al 17 also characterized the coefficient factor of polyacrylonitrile fibers that have a bean-shaped cross-sectional area using an optical microscope and gravimetrically, and obtained a range of 1.26-1.54.…”

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.

“…The methods used for determining the cross-sectional area of fibers with an irregular cross-section [17,18] are difficult and yield only a statistical estimate of the area. Also, the method [15] is applicable only for homogeneous fibers.…”
