“…It is difficult to compare the experimental data obtained from the literature (Table 3) given the types of yarn used, its maturity, the environmental conditions in which these plants were grown, and the methods used to perform the tests, especially to determine the rate of stress. Nevertheless, it was possible from the literature [1,5,8,13,15,19,20,22,28,[34][35][36][37] to synthesize the results on plant yarns in tensile static tests (Table 3). The strength value obtained from our experiments for sisal yarn equates to 148 MPa for GL = 100 mm in N = 20 tests, which is similar to the reference for N = 30 [13].…”

A designer of sustainable biocomposite structures and natural ropes needs to have a high confidence interval (95% CI) for mechanical characteristics data of performance materials, yet qualities for plant-based fibers are very diverse. A comprehensive study of the elements that enhance the performance of biocomposites or sustainable ropes created from vegetable fibers is necessary. The current study included five groups with varying numbers (N) of tests of 20, 40, 60, 80, and 100 on the mechanical characteristics at room temperatures. The purpose of this study was to determine how changing N affects the mechanical properties of sisal yarn. These properties include its strength, Young’s modulus, and deformation at rupture. A significance testing program including more than 100 tests was performed. Owing to the heterogeneity of the plant yarn, each group received more than 20 samples at a gauge length (GL) of 100 mm. The tensile strength characteristics of sisal yarns produced a wide range of findings, as is common for natural fibers, necessitating a statistical analysis. Its dispersion was explored and measured using the statistical methods. The Weibull distribution with two parameters and a prediction model with a 95% confidence level for maximum likelihood (ML) and least squares (LS) were used to investigate and quantify its dispersion.

“…From their findings, the higher TS (152.7MPa) and TM (9.1GPa) were noticed for untreated jute yarn compared to alkali and silane treated yarns. Similarly, untreated jute yarns yielded highest mechanical behaviour than the yarns immersed in normal water and exposed to the temperature (at 105⁰C) was experimentally proved by Ben et al (2020).…”

Jute fibres is of great interest to be used as reinforcement in thermoset or thermoplastic composites, in order to provide positive environmental benefits in-terms of degradability, abundance, low density, nominal cost and recyclable. During fabricating the composites, researchers facing complications such as high water absorbing (WA) character, poor incompatibility of fibre with resins, quality variations in fibres, low thermal stability, etc. Therefore, chemical treatments are considered and it will be the most effective way to enhance the interfacial bonding with matrix, improve mechanical strength and less WA as well. Many research works were carried out on the influence of chemical treatment on the properties of jute fibre and their composites. The investigated treatment methods and the impact of chemical treatment on the properties of jute fibre reinforced polymer composites are comprehensively presented in this review.

The development of wind turbines for regions with low wind speeds imposes a challenge to the expansion of the corresponding energy generation capacity. The present work consists of an evaluation of the potential carded jute fiber and jute yarn to be used in the construction of a wind blade for regions of low wind intensity. The fibers used were supplied by Company Textile of Castanhal (Castanhal-Para-Brazil) and used in the study without chemical treatment in the form of single-filament fibers and yarns with a surface twist of 18.5°. The composites were produced through the resin infusion technique and underwent tensile and shear tests using 120-Ohm strain gauges and a blade extensometer to obtain the Young’s modulus. In the analysis of the results, the ANOVA test was applied with a 0.05 significance level, followed by Tukey’s test. The results showed that long, aligned jute fibers can be a good option for laminated structures applied in composites for small wind turbine blades.
