Tensile Behavior and Statistical Analysis of Washingtonia Filifera Fibers as Potential Reinforcement for Industrial Polymer Biocomposites

Mechanical properties and statistical analysis of Syagrus Romanzoffiana palm cellulose fibers

“…A broad dispersion of findings, a characteristic of natural fibers, clearly needs a rigorous statistical investigation. A similar behavior has been seen in the case of Washingtonia Filifera fibers presented by Dembri et al, 6 as well as jute fibers according to Wang et al 38 and Saidia et al 34 at a GL of 50 mm and sisal fibers studied by Belaadi et al 33 at different GLs and Gahgah et al at a GL of 100 mm. 36 The usual behavior of the tensile curve for Syagrus Romanzoffiana fibers may be divided into two regions, as shown in Figure 4(b): The initial quasi-linear region at the beginning of the curve is the total fiber load and the free redirection of the fibrils in the direction of the tension.…”

“…Furthermore, the Weibull modulus of SR fiber for Young's modulus (m E ) consistently declines as the number of tests increases. A same pattern using WF fibers was found by Dembri et al 6 It's also vital to remember that various estimators estimate the parameters of the 2P Weibull distribution slightly differently. For instance, using the Mean Rank (Herd-Johnson) estimator, we get m σ = 4.5, m E = 2.1, and m ε = 3.7 for the minimal values of the Weibull modulus for N = 200.…”

“…This phenomenon has been found in jute and Washingtonia Filifera fibers. 6 Figure 6(a)-(b) shows the difference across test groups in the exponential fit, modulus of elasticity, and connection of failure strain to tensile strength using a 95% confidence range for exponential model prediction. Figure 6(a) shows that Young's modulus increases with increasing tensile strength, but decreases with increasing strain at break (Figure 6(b)).…”

“…[2][3][4][5] The last 10 years have seen a substantial increase in interest in composites reinforced with natural fibers across a range of industrial sectors. [6][7][8] In these composites, a wide range the naturally occurring fibers, notably sisal, flax, jute, kenaf or hemp can be used as reinforcement or substances to meet a variety of mechanical or environmental needs. [8][9][10][11][12] Particularly noteworthy are the high-performance composites made from biomass, which are in high demand among customers and the composite sector.…”

“…The Weibull distribution shows that treated fibers have higher values (m σ = 2.28 for strength, m E = 3.20 for Young's modulus) than untreated fibers (m σ = 2.23, m E = 2.76), indicating the effect of NaHCO 3 on flax fiber qualities. Dembri et al's recent study 6 examined Washingtonia Filifera fiber performance utilizing a tension test at 50 mm gauge length. The results, reported when 150 fibers were tried in five series, showed a growth in average tensile stress (σ), strain (ε) and Young's modulus (E) as batch numbers increased from 30 to 150.…”
