“…Sclerenchyma fibers are part of the support tissue in the plant fibers, having a thickened secondary wall and prominent lumens structured by spiral vessels cellulose fiber along with lignin (Cosgrove, 2005; Zhong & Ye, 2015). The cellular structure of the fibers of the present work (Figure 5i–l) are similar to other lignocellulosic fibers such as Agave tequilana (Espino et al, 2014), peach palm fiber (Diaz, Silva, & D'Almeida, 2016), and Juncus effusus (Maache, Bezazi, Amroune, Scarpa, & Dufresne, 2017). In the case of sclerenchyma fibers, significant differences were found in the cells' area and Feret diameter (Table 2) when the two maturity stages were compared (Figure 5e,g), with these parameters decreasing as the ripening process progressed (17.59% and 5.66%, respectively).…”

The cuajilote (Parmentiera edulis D.C.) tree produces fibrous fruits with a high content of lignocellulosic compounds. However, this fruit and their fibers have been scarcely studied. For this reason, an integral study of their cellular architecture, physicochemical, micromechanical, and structural properties in two maturity stages were carried out. Physicochemical tests, light, confocal and electron microscopy, microindentation, and X‐ray diffraction were used for the characterization of fruit and their fibers. Chemical analysis showed that the unripe fruits have the highest cellulose content (42.17%), but in ripe fruit the cellulose content decreases (32.76%) while lignin content increases from 35.26 to 40.79%, caused by the lignification of the sclerenchyma fibers. Microstructural and micromechanical studies in the different regions of the fruit provided relevant information about its cellular architecture, distribution of lignocellulosic compounds and its role in the micromechanical properties of their fibers. The thickening cell wall of sclerenchyma fibers was caused by the cellular lignification of the ripe fruits. According to the physicochemical and structural studies, cuajilote fibers are comparable to other fibers obtained from crops rich in lignocellulosic compounds. The current study provided new knowledge about the cellular architecture of fruit and criteria for selecting the ripening stage adequate for the extraction of cellulose or lignin. Furthermore, information regarding the micromechanical properties of their fibers and which structural arrangement could be more convenient for mechanical reinforcement of biodegradable materials was obtained.

“…Only the hemp samples presented prominent peaks at 2θ between 15.9° and 16.2° (101 ̅ ). These results are compatible with other analyses about the crystalline structure of cellulose (Park et al 2010;Poletto et al 2014;Ferreira et al 2015a;Diaz et al 2016). The peaks at 2θ from 33.9° to 34.1° (040) were not included in the deconvolution analysis due to their very low intensity (Diaz et al 2016) (Fig.…”

The influence of elevated temperatures on mechanical behavior was studied for curaua, hemp, and sisal natural fibers. Tensile tests were performed on fibers heated at 100 °C, 150 °C, and 200 °C for 24 h, and reference samples were maintained without thermal treatment for comparisons. The cross sectional area of the fibers was measured using a scanning electron microscope (SEM), and the image analysis was performed using the open source software Fiji/ImageJ. These data allowed the computation of the tensile stresses and the correlation of the fiber morphology with its macro-mechanical behavior. The thermal degradation behavior of the natural fibers was measured via thermo-gravimetric analysis (TGA) and X-ray diffraction (XRD). The morphological and mechanical characteristics were described and discussed on a microstructural basis. The results showed that the loss of moisture leads to a significant increase in tensile strength before reaching the limits of the degradation range.

“…The fibrous cells (Fig. 2c) are connected to each other via the lignin-rich medial lamella (Diaz et al, 2016;Beakou, Ntenga, Ateba & Ayina, 2008). Figure 2b shows the morphology of the overall microstructure of the JE fiber bundle which has rough cavities on its outer surface, with small voids similar to those observed by (Indran et al, 2014).…”

This study aims to assess the morphology and properties of fibers extracted from a wild natural plant largely available in Algeria known as Juncus effusus L. (JE). The morphology and diameter of the fiber bundles extracted from the stem of the JE plant were characterized by optical and scanning electron microscopy. The functional groups of the extracted lignocellulosic JE fibers were studied by FTIR, their thermal degradation behavior was investigated by TGA and their crystallinity was determined using X-ray diffraction technique. In addition, mechanical characterization was carried out using tensile tests on the lignocellulosic fiber in order to evaluate their strength, strain at break and Young's modulus. In view of the dispersion in the obtained experimental results, the latter were analyzed using the Weibull statistical laws with two and three parameters.
