“…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.
