Abstract

In recent years, the usage of natural fibers as reinforcement in composite materials has acquired significant attention because of their remarkable benefits, which include being lightweight, inexpensive, and biodegradable. The current work involved surface alteration by alkali treatment on sorghum fibers by varying concentrations of NaOH (5, 10, and 15 wt %) to overcome the disadvantages of employing natural fibers, which include lower melting point, increased moisture absorption, and lack of bonding. In an epoxy matrix, these fibers have been utilized as reinforcements. The effects of fiber modification and varying sorghum fiber weight proportions (5, 10, 15 and 20 wt %) on mechanical and water-absorbing qualities were examined. The alkali treatment effectively enhances interfacial bonding among sorghum fiber surface and epoxy matrix, thereby enhancing the overall fiber strength and leading to superior mechanical performance. Results from water absorption tests revealed that composites reinforced with NaOH-treated sorghum fibers exhibited significantly lower water absorption compared to their untreated counterparts, indicating improved moisture resistance.
