Development of Bambusa tulda fiber-micro particle reinforced hybrid green composite: A sustainable solution for tomorrow's challenges in construction and building engineering

Abstract

Researchers are continually focusing on natural alternatives to synthetic materials due to the ongoing rise in global warming and sustainability concerns. Interest in natural fiber reinforced polymeric composite (NFRPC) is growing steadily due to their low cost, biodegradability, lightweight nature, and superior lifecycle. NFRPCs are used everywhere, from manufacturing automobile interior parts to constructing engineering projects. The current experimental investigation focuses on developing a hybrid composite reinforced with Bambusa tulda fiber and microparticles . Bamboo biomass, collected as waste from nearby industries, is converted into valuable bamboo micro-particles through chemical treatment. Hybrid composites have been developed with a 30 % bamboo fiber loading, varying the weight fraction of bamboo microparticles from 0 to 10 with intervals of 2.5 wt%. The experimental investigation revealed that adding micro particles to the bamboo fiber reinforced composite resulted in a 12.72 % maximum increase in tensile strength and a 19.79 % maximum increase in flexural strength . The addition of microparticles beyond 5 % resulted in agglomeration, leading to a decrease in properties. Based on the comparative analysis of the results, it can be concluded that the developed composite has the potential to be used in the construction and building engineering industries.
