“…( 2) and ( 3), it can be seen that both Weibull parameters,  and  , have very similar mathematical coefficients. This then suggests that, as for other lignocellulosic fibers [33][34][35][36][37][38], a hyperbolic type of mathematical equation is the best statistical correlation between the density and the diameter of fique fibers. As a final remark, it is worth speculating that an inverse correlation between density and diameter, such as the hyperbolic in Eq.…”

“…In terms of diameter dimensions, it has been recognized that thinner fibers, with smaller diameter, are relatively stronger and stiffer [20][21][22][23][24][25][26][27][28][29][30][31][32]. More recently, the density of several lignocellulosic fibers was also found to vary inversely with the fiber diameter [33][34][35][36][37][38]. This might also be the case of the relatively unknown fique fiber, which has been the subject of few research works [39,40].…”

Environmental considerations in addition to technical, economical and societal benefits are contributing to promote the substitution of natural fibers for glass fiber in polymer matrix composites. However, natural fibers are heterogeneous in their dimensions, specially the cross section diameter, which plays an important role in their physical properties. The fibers extracted from the leaf of the fique plant (Furcraea andina) are a promising stiff natural fiber for composite reinforcement. In this work, a statistical analysis of the density of fique fibers using the Weibull methodology was performed. An attempt to correlate the fiber density with the diameter, precisely measured by means of a profile projector, was carried out. The results revealed an inverse dependence, adjusted to a hyperbolic equation, between the fique fiber diameter and corresponding density.

“…Additionally, inverse diameter correlations were also recently found for the density 37-42 and the elastic modulus 37,40,[43][44][45] . Using the Weibull analysis in all these properties -strength (σ), density (ρ) and elastic modulus (E) -a simple hyperbolic type of mathematical adjustment was always obtained, similar to Equation 1.…”

“…Based on the similarity between Equation 7 and 8 it is suggested that, as in other lignocellulosic fibers [34][35][36][37]40,[43][44][45] , a hyperbolic type of mathematical equation is a simple and reliable statistical correlation between the elastic modulus and the diameter of fique fibers. In practice, this indicates that thinner fique fibers are stiffer than thicker ones.…”

“…Wood fibers with larger diameters (0.54 mm) and higher roughness led to easy generation of gaps between fibers and the HDPE matrix. At the same time, HDPE was able to penetrate only the surface layer of the wood fibers, leaving the center part of the fibers in their original honeycomb structure . Thus, the density of WPCs decreased with the increase in the diameter of wood fiber.…”

Use of high-quality wood fibers as reinforcement materials in wood-plastic composites (WPCs) significantly improves the overall performance of the resulting WPCs. This study focused on the preparation of various types of wood fibers for subsequent use in WPCs. Further, effects of moisture content, wood species, and form of raw material on the quality of prepared wood fibers and on the mechanical properties of wood fiber-reinforced high-density polyethylene were comprehensively investigated. The main findings indicated that the overall size of wood fibers increased significantly with the initial moisture content of raw materials; the best morphological features of fibers and the best corresponding mechanical properties of WPCs were obtained for an initial moisture content of 30 wt%. The lengths and diameters of wood fibers prepared from veneers were larger than those of fibers prepared from chips. A wood fiber diameter between 0.21 and 0.29 mm (60-80 mesh) and a length to diameter ratio between 5 and 8 yielded the best mechanical properties for the resultant products.
