Abstract :

The present study hypothesises that the tensile strength of wood-duroplastic composites (WDPC) is influenced by the size and shape of wood waste particles. The aim of the research was to assess whether variations in the structural composition of wood waste particles impart a noticeable influence on the resulting properties of the 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. Subsequently, composite specimens were developed using biopolyurethane binders. Tensile strength tests were conducted after 30 days of curing. The present study showed 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 show superior tensile strength. The present study contributes to the field of sustainable waste reuse strategies and presents practical insights into the development of engineered wood products. Recent Publications 1.
