Abstract

This research investigates the mechanical properties of bamboo fiber-reinforced unidirectional epoxy composites, focusing on two bamboo species, Bambusa Vulgaris (Baijja bamboo) and Melocanna Baccifera (Mulli bamboo). The study examines the tensile, flexural, and impact properties of composites fabricated from bamboo fibers extracted from different sections (top, middle, bottom) of the bamboo culm. The composites were prepared using a hand layup method and subjected to mechanical testing according to ASTM standards. Results show that the middle portion of both bamboo species exhibits superior mechanical performance compared to the top and bottom portions. Specifically, the middle section demonstrates higher tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength. The enhanced properties of the middle section are attributed to factors such as fiber alignment, density, and composition. The findings suggest that utilizing bamboo fibers from the middle portion can lead to the development of high-quality composite materials suitable for various engineering applications, particularly in automotive part manufacturing. This research underscores the importance of understanding the mechanical behavior of bamboo composites for optimizing their use in sustainable and eco-friendly industrial products.
