The jute fiber is one of the strongest lignocellulosic fibers with different applications such as fabrics, ropes as well as engineered composites for automobile parts. In this study, the jute yarns were exposed to different temperatures of the thermal cycles (22°C, 40°C, 80°C, 105°C and 150°C). The mechanical tests were conducted using the 3R Syntax machine and the experimental results depended on different temperatures of thermal cycles were recorded. The mechanical properties of jute yarns decrease with the increase of temperature of the thermal cycles.

“…This variability is due to the variability of the climatic conditions and the cultivation conditions of the plant. The sisal yarns with Algerian origin were studied by Belaadi et al [70] and the obtained results show that the average diameter value is 2.04 ± 0.26 mm. The sisal yarn is made of a bundle of z-twisted fibers with a twist level about 80 tpm, Figure 8.…”

This work aims to investigate the physical and mechanical properties of sisal fiber and yarn of Moroccan origin. The cellulosic and non-cellulosic constituents of the Moroccan sisal fiber were identified by FTIR spectroscopy. The thermal properties were studied by thermogravimetric analysis. The hydrophilicity of the fiber was evaluated by the contact angle. The results show that the sisal fiber has a low thermal stability. The mechanical properties of the fiber analyzed by the Impregnated Fiber Bundle Test (IFBT) method show that the porosity of the impregnated yarns and the twist angle of the yarns influence the elastic modulus of the sisal fiber. The physical and mechanical properties of the manufactured sisal yarns were also characterized and analyzed. The obtained results reveal an interesting potential to use the Moroccan sisal fiber in development of bio-sourced composite materials.

“…Where F(χ) is the probability of survival depending on the parameter χ, m is a dimensionless shape parameter directly related to the dispersions of the experimental data, and χ0 is a local parameter representing an average value of the parameter χ (minimum life of stress, strain and modulus), [4,16,18,27]. The value F is evaluated by a metric estimator (value of an average rank) [17][18][19]:…”
