In this study, a novel approach has been presented for manufacturing composite fiberboard by incorporating waste walnut shell powder particles into epoxy resins. The aim of this research is to evaluate the mechanical properties and micro-structural characteristics of the resultant composite plate. The composite fiberboard specimens were prepared and various tests were carried out to assess the composite's strength, stiffness and energy absorption capabilities. Furthermore, Scanning Electron Microscope (SEM) analysis was performed to study the microstructure of the composite and for understanding of the composite's morphology and the distribution of filler particles within the resin. The experimental outcomes demonstrated that the composite exhibited promising mechanical properties Moreover, the SEM analysis revealed some voids formation between the waste walnut shell particles and the epoxy matrix, contributing to reduced mechanical performance.
