Distinctive study on banana/sisal fiber hybrid composites filled with nano marble dust particles

Abstract

The increased popularity of synthetic fibers has been hampered by high production costs and environmental concerns, despite the former's superior stiffness and strength. As a result, it's reasonable to consider devoting considerable effort to finding natural fibers that can replace synthetic ones in various applications. Because they have superior mechanical and thermal qualities over synthetic fibers, hybrid fibers are typically preferred. Natural fibers have the advantage of being more pliable and robust, but they cannot repel water. Most of the earlier research findings are very limited in determining the effects of marble dust particle addition on the two different types of natural fiber-reinforced epoxy composites. This experimental research work has incorporated a novel approach to fill this gap. Researchers have invented novel materials that could reduce the usage of thermoplastics to reduce the environmental issue. Cross-linking bond ability enhancement between the matrix and fiber has been done by adding nano marble dust particles. Short banana and sisal fibers (1 to 2 cm in length) are combined via injection molding with a polypropylene matrix to fabricate a hybrid composite with Nano marble dust particles (50 to 60 nm). The composites' flexural strength, impact strength, thermal conductivity, and water absorption enhance by adding Nano marble dust particles as filler material. It notices that banana and sisal fiber added composite contributed better tensile properties than Nano marble dust particles added composites.
