“…Hence, in this work, different amounts (wt%) of MMT clay have been used to optimize the composite's strength, as MMT provides better properties when uniformly dispersed into the polymer system. Napier fiber was selected in this study since several reports indicated its potential to be utilized as a reinforcement constituent in polymer composites . To enhance the knowledge in the field of composites, this is the first time an investigation has been conducted on Napier fiber reinforced nanomodified epoxy composites.…”

The tensile, flexural, and morphological properties of Napier fiber reinforced nanomodified epoxy composites were investigated. Untreated and alkali‐treated Napier fibers, as well as nanoclay and epoxy resin, were used to fabricate Napier fiber reinforced nanomodified epoxy composites by using cold press compression machines. Napier fiber was treated with 5% dilute sodium hydroxide (NaOH) solution for 6 h. Varying amounts of nanoclay filler (3, 5, and 10 wt%) were mixed with the epoxy resin prior to fabricating the Napier fiber reinforced nanomodified epoxy composites. The results of mechanical testing indicated that the alkali‐treated Napier fiber reinforced nanomodified epoxy composites incorporating 5 wt% nanoclay exhibited the highest flexural and tensile properties. Morphological analysis was then conducted to further analyze the fractured specimens following the mechanical tests. The scanning electron microscope images of the Napier fiber reinforced nanomodified epoxy composites that contained 5 wt% nanoclay revealed good interfacial bonding between the matrix and the reinforcement.

“…Similarly, the length of the natural fibre significantly influences the tensile and flexural properties, as well as the damage mechanisms of Pennisetum purpureum-reinforced composites [26]. Recently, several studies have indicated that Pennisetum purpureum grass fibres can potentially be used as a reinforcement material in polymer composites [27][28][29][30][31].…”

“…The data shows that for the alkali treated fibres the maximum unit break increased significantly while the % elongation at break increased slightly. In untreated fibres, hemicellulose and lignin continue to spread in the interfibrillar area untying the cellulose chain from one another [20]. The cellulose chains are continuously in a state of constraint.…”

In this study, Napier grass (Pennisetum purpureum) fibres which hold 59.19% cellulose, 21.35% hemicellulose and 7.26% lignin were comprehensively characterized to evaluate their potential as building material for medium density fibreboard (MDF). The purpose of this work was to examine the effects of sodium hydroxide solution as an alkali pre-treatment in determining the best condition for lignin removal in Napier fibres. The treatments were conducted using NaOH concentrations of 0.5, 3.0, 5.5, 8.0, 10.0 and 10.5 wt. %. The morphology of the fibres was observed using scanning electron microscope (SEM) and its chemical compositional changes was confirmed by Fourier transform infrared spectroscopy (FTIR) analysis. The study showed that the morphological observation demonstrated that the best concentration for the removal of lignin in Napier fibre was 10.5 wt. % NaOH solutions. It has been found that as the alkali concentration increased, the surface of the fibre becomes rougher which reduced the void content in the fibres. The fibres that were alkali-treated using NaOH solutions of various concentrations as well as the untreated one were subjected to single fibre testing. From the results of the single fibre testing, it is revealed that the 10.5% alkali-treated Napier grass fibres yielded the maximum and highest strength. This further signifies that alkali pre-treatment has significant impact on the production of MDF board from the non-wood fibres biomass such as Napier fibre.
