“…As a result, there is a significant focus on plant fibers and waste, as it offer considerable potential [1][2][3][4]. Biomaterials have been developed for use in industries such as shipbuilding (using composites with epoxy resin, polyester, etc), aviation, automotive (using composites with plastic matrix, polymer, etc), and civil construction applications (using composites based on cement and plaster), and have garnered significant research interest [5][6][7]. Natural fibers and waste have replaced synthetic fibers as reinforcement for these composites because it possess high mechanical qualities in their natural state or following chemical, thermal, or mechanical treatments [8].…”

This study aims to investigate the viability of untreated sisal fibers (N.F.), NaOH-treated sisal fibers (NaOH.F.) and cellulose extracted from sisal (CELL.F.) as an alternative to synthetic materials to produce biocomposites. The main objective was to conduct an in-depth study of the properties of these fibers whose aim is to limit matrix/fiber slippage and improve adhesion by modifying reinforcement surfaces, and to improve the efficiency of sisal fibers as reinforcements for composite materials using various analytical techniques including Fourier transform infrared spectroscopy, scanning electron microscopy, x-ray diffraction, and thermogravimetric analysis. In addition, the study aimed to produce a composite material by reinforcing plaster with the aforementioned fibers and then compare the mechanical and physical properties of the resulting material. The results showed that cellulose fibers exhibited higher mechanical strength and better compatibility with the plaster-matrix compared to sisal fibers by an increse of 324% in their tensil strength compared to natural sial fibers. In particular, the flexural strength showed a significant increase of 35% in the cellulose fiber reinforced composite. The reinforced composite material exhibited improved properties such as better flexural strength, increased absorption by 12.8% and descres the density by 21.3%, highlighting the promising prospects of cellulose fibers in advancing biocomposite technology.

“…1 This novel category of materials are composed of biodegradable polymers or natural fibers, resulting in an innovative material possessing mechanical characteristics akin to those of conventional glass fiber-based composite materials. 2 These eco-friendly, lightweight, and sustainable materials hold the promise of revolution of various industries, such as aerospace, 7 construction and building material, 6 oil and gas industry, 227 marine and shipbuilding, 8 electrochemical, 5 textile and apparel manufacturing, electronics, 3 and pharmaceuticals. 4 Although smart biocomposites hold significant achievements, the prediction of their deformation mechanism remains a challenge because they may damage differently by compressive or tensile strain unlike metals or traditional composites.…”

“…As materials designed for industrial uses or for civil engineering have grown during the past three decades. Due to a number of factors and bene ts, such as strong mechanical and physical qualities, cheap cost, low density, biodegradable, non-toxic, and there are signi cant amounts that go wasted, the focus on plant bers and plant wastes are of considerable interest [1][2][3][4].The development of biomaterials for use in a variety of industries, such as shipbuilding (composite with an epoxy resin matrix, polyester...), aviation, automotive (composite has a plastic matrix, polymer...), and even the composite developed for civil construction applications, such as composites based on cement and plaster, has received signi cant research interest [5][6][7] Natural bers and waste have replaced synthetic bers as reinforcement for these composites because they have high mechanical qualities in their natural condition or as well in chemical, thermal, or mechanical treatments [8].…”

In the context of attempts to protect the environment and the ongoing exhaustion of fossil resources, using biomass raises significant environmental concerns. From this approach, sisal fibers and the cellulose extracted from them are used as bio-reinforcement in the production of composite materials. The first part of this paper will examine the effects of sodium hydroxide treatment on the mechanical characteristics of natural sisal fibers. Then, the morphological properties of the surface of the fibers were determined using scanning electron microscopy (SEM). X-ray diffraction was performed on the treated and untreated fibers. The results showed that the cellulose and the treated fibers had a greater crystallinity index than the untreated fibers. The results of the FTIR spectroscopic examination were strongly congruent with the results of the XRD and SEM analyses. The ATG, which was performed on both natural sisal fibers, treated sisal fibers, and cellulose fibers, also showed that treatment of the fibers increased their thermal resistance and stability. According to research on composite materials made of plaster reinforced by fibers, increasing the sisal treated fibers content in plaster molasses to 1.25% led to a greater improvement in the mechanical and physical characteristics with a rise of 35% in resistance to bending. Additionally, when applying the cellulose fibers extracted from sisal as a reinforcement to the plaster-based composite material, we obtain an incensement in the resistance bending by 48%.
