| Description: |
International audience ; The focus of our research work is on the fabrication and characterization of jutereinforced composite. The material is manufactured by vacuum contact molding, with stratification conducted according to a well-detailed protocol. This study investigates the effects of alkali treatment on the mechanical and structural properties of jute fabric-reinforced polyester composites. Jute fabrics underwent chemical treatment with sodium hydroxide (5% of NaOH by weight) for five different exposure times (raw, 1, 3, 6, and 24 hours) followed by a pressure contact molding process. In physical characterization process, we focused on determining the reinforcement volume ratio and measuring the density of the composites. To evaluate their mechanical properties, we conducted tensile tests, which help us understand how the materials behave under stress. For structural characterization, we employed several advanced techniques, including X-ray diffraction (XRD) to analyze the crystalline structure, Fourier Transform Infrared spectroscopy (FTIR) to investigate chemical compositions, X-ray tomography for a detailed 3D view of the internal pore structure, and scanning electron microscopy (SEM) to observe the surface morphology. These methods collectively provide a comprehensive understanding of the materials' properties and performance. The results showed that alkali treatment significantly influenced the mechanical properties; i.e., the composites reinforced with fabrics treated for 1 and 3 hours exhibited the highest tensile strength (improvement by 20% and 9%, respectively) compared to composites reinforced with raw fabrics). XRD analysis revealed an increase in crystallinity index after treatment, particularly for an hour. FTIR spectra showed changes in chemical groups after treatment, indicating the removal of certain constituents. Image processing using X-ray tomography offers non-destructive, 3D analysis with high resolution, while conventional methods are simpler and more cost-effective. This technic ... |
