PRODUCTION AND MECHANICAL CHARACTERIZATION OF MUSTARD HUSK POWDER REINFORCED EPOXY COMPOSITE

Abstract

This research work deals with the production of a fiberboard using mustard husk powder (a type of agricultural waste) and epoxy resin, which can be used as an alternate to the plywood. The aim of this research work is to determine the mechanical and microstructural properties of this novel composite. Various tests were conducted on various specimens to evaluate its strength and energy-absorbing capacity. Using a scanning electron microscope (SEM) the microstructure of the created fiberboard was also examined in order to understand the morphology and filler particle distribution within the resin. After fabrication and testing, it has been observed that the composite fiberboard has tensile strength of 11.5 MPa, flexural strength of 33.5 MPa, Impact strength of 19.65 J/m² and hardness of 20.68 (Vicker’s) which are comparable to those of the composites made from epoxy mixed with other agricultural wastes such as walnut shell powder, pomegranate peel powder etc. The SEM study revealed perfect bonding between the epoxy and the mustard husk powder particles which enhanced the mechanical properties, making it a suitable and environment friendly composite.
