Thermo-mechanical properties of sodium chloride and alkali-treated sugarcane bagasse fibre

The experimental characterization of mechanical and thermal properties of treated and raw sugarcane bagasse fibre hasbeen studied. The bagasse fibres are treated with sodium chloride (NaCl) and sodium hydroxide (NaOH) solutions. TheNaOH treated fibres show better structural and thermal properties than other two types. SEM image of alkali-treated fibresreveals that the bundles of fibres are mainly composed of thin parenchyma cell walls. The fibres are joined with each otherwhich improves the mechanical properties. The statistical analysis is also performed using ANOVA one-factor method.From ANOVA, the significant difference between the dependent parameters and the various chemical treatments aredetermined. The results show that the NaCl and NaOH treated fibres significantly improve the mechanical properties andthermal stability

INFLUENCE OF CHEMICAL SURFACE MODIFICATION ON MICRO-WEAR CHARACTERISTICS OF SUGARCANE NANOCELLULOSE EPOXY NANOCOMPOSITES

The waste sugarcane bagasse is the primary agricultural biomass of sugarcane industry and its main constituents is cellulose. These waste sugarcane bagasse can also be applied as reinforcement material in polymer matrix composites. In this present work, the nanocellulose fibers extracted from sugarcane bagasse using salt solution and alkaline treatment process. Sugarcane nanocellulose fiber reinforced epoxy nanocomposites were manufactured by wet layup method. This investigation has been conducted to exhibit the utilization of plant cellulose fiber as the potential reinforcement of synthetic fibers in tribo-composites. The dry sliding wear experiments designed and carried out as per central composite design to determine influence of 3 variable factors such as sliding velocity, sliding distance and load on the wear characteristics of epoxy nanocomposites. From ANOVA (Analysis of variance), it is observed that all three independent parameters plays an important role in the wear characteristics of epoxy nanocomposites, as proven from scanning electron microscope. Simultaneously minimize these tribological characteristics, desirable values of the parameters were depicted to be 5.94 m/s, 5 km and 5 N for sliding velocity, distance and load respectively. From normal probability curves, it is signified that there is a good agreement within the RSM models and experimental results.&nbsp
