In this study, we utilized the material design library in Ansys Product 2022 R1 to analyze the impact of short plant fibers on the mechanical properties of epoxy resin. We employed the representative volume element (RVE) approach and examined different volume fractions up to 50%. The technique employed in this study was multi-scale modeling based on the finite element method (FEM) for numerical homogenization. Subsequently, we used the same software to develop a five-layer laminated composite. The samples were based on epoxy resin enriched with short plant fibers at fractions of 20% and 30%, as well as pure epoxy resin. The laminated composites were reinforced with carbon fibers. The objective of this study was to analyze the mechanical response of each sample during a tensile test, focusing on multiple parameters. The sought-after results included total deformation, directional deformation, equivalent and elastic stress (Von-mises). The samples containing epoxy resin enriched with 30% of short hemp fibers exhibited remarkable mechanical strength compared to the other samples. These results suggest that the incorporation of short hemp fibers into the matrix led to a significant improvement in the mechanical strength of the composite.

“…Recently, Babty et al [16] characterized the swelling behavior of a biomaterial based on argan nut shells in the presence of water. The authors first sorted and sieved the ground ANS, then mixed the resulting powder with urea formaldehyde to prepare three biomaterials with different ranges of shell grain sizes.…”

The argan tree (Argania Spinosa) grows mainly in Morocco. This forest species, also called iron tree, covers about 830000 ha of Moroccan territory. Virtues of this argan oil are multiple: uses for cooking, medicines, or cosmetics. The objective of this work is the valorization of the argan tree, and especially in its shell, which remains poorly exploited and which is sold by the premises at low prices for use as a fuel in the Moorish baths and bakeries. Argan shell is the reinforcement of this bio-composite. For this, the shell is ground, sieved and separated into five different diameters d. Then, the preparations of the three ranges, each of which is composed of proportions (20%, 60%, 20%) of increasing diameter of particles. Each particle range is used as reinforcement in a matrix of urea formaldehyde and water as a non-polluting solvent. Using a traction machine, the Young module and the breaking stress of the three biomaterial ranges were determined. Our results show that the Young module of first range (R1) remains superior to that of other two ranges and also has a high breaking voltage. Then the bending measurements were made by the three-point machine MTS EM Flexion. Our results show that the R1 has a greater bending stress than the other two ranges.

“…Additionally, the expense of addressing environmental damage due to agricultural waste can be considerable. Consequently, there is an urgent need to convert the lignocellulosic-based waste into value-added products [5], such as carbon-based materials [6,7], biogas [8,9], biofuels [10,11], engineering plastics [12,13], biocomposites [14][15][16]. By implementing waste-to-product strategies, it is possible to create a more efficient, resilient, and sustainable economy while simultaneously reducing waste and its environmental impact.…”

Banana peels (BP) are the outer covering of a banana fruit and are usually discarded as abundant and underutilized waste from banana production and consumption. This work investigated the bioresource for one-pot preparation of carboxyl cellulose nanofibers (CCNF) using the nitro-oxidation method. Briefly, BP was added to a mixture of HNO3 and NaNO2 at 30-50 o C for 6 h. To characterize the obtained material, different methods, including X-ray diffraction, TEM images, FTIR spectroscopy, EDX spectroscopy, and acid-base titration, were used. TEM images reveal that the nanofibers were mainly formed with a diameter of roughly 20-50 nm. Moreover, the results of FTIR, EDX, and titration proved the formation of carboxylic acid (-COOH) groups in CCNF with an amount of 4.9 mmol/g, or 22 wt%. This high carboxyl content makes CCNF an ionexchange material, thereby enabling the development of new applications. Compared with traditional multistep processes for the preparation of cellulose nanomaterials, the current approach is simpler, uses fewer chemicals, and consumes less energy. Overall, these successful results not only valorize potential banana peel waste but also introduce an advanced material for further use.
