Analysis of the structural parameters of engineered wood

This study hypothesises that the tensile strength of wood-duroplastic composites (WDPC) is influenced by wood waste particle size and shape. The research investigated whether variations in the structural composition of wood waste particles have a significant impact on the properties of composite materials. The analysis of the three types of wood waste—door production, packaging, and demolition waste—was conducted following mechanical and chemical treatment. The characterisation of particles was conducted through granulometric analysis and morphological evaluation using ImageJ software. Composite samples were then developed using biopolyurethane binders. Tensile strength tests were conducted after 30 days of curing. The findings of the present study indicated that the morphology of the particles, especially their aspect ratio and circularity, had a significant impact on the strength of the composite materials. Despite their comparatively greater density, attributable to their aluminium content, samples of door waste did not demonstrate superior tensile strength. The present study makes a contribution to the field of sustainable waste reuse strategies and presents practical insights into the development of engineered wood products.
