Experimental Study on the Development of Particle Board Using Local Materials

Abstract

The escalating demand for sustainable materials necessitates the development of high-performance bio-composites derived from agricultural wastes. This study explores the effects of varying proportions of melon husk, groundnut shell powder, and bone powder on the mechanical and water absorption properties of bio-composites using melamine formaldehyde as the binding matrix. Nine formulated samples (S1 - S9) were analyzed for mechanical strength, most importantly tensile strength and flexural strength, and also, water absorption. Results showed that Sample S6 containing 100 % melon husk hada lower tensile strength of 21.62 MPa and flexural strength of 36.89 MPa while Sample S7 made with 100 % groundnut husk had a tensile strength of 14.23 MPa and flexural strength of 30.31 MPa. However, Sample S5 with a hybrid formulation of 20 % melon husk, 70 % groundnut husk and 15 % bone powder gave the highest tensile strength of 28.96 MPa and flexural strength of 46.66 MPa. Using Grey Relational Analysis over the nine samples, considering nine properties in all, S5 was found to have the optimal composition with a Grey Relational Grade (GRG) of 7.32. All samples recorded high mechanical values well above the required threshold for woodwork and furniture and therefore, may be explored as alternative materials for structural applications.
