Resumo: ABSTRACT The aim of this research was to evaluate the effects of removing fines on the physical and mechanical properties of high-density particleboard produced by mechanical processing of Caryocar villosum (pequiá), Tachigali myrmecophyla (tachi-preto) and Hymenolobium excelsum (angelim-da-mata) Amazonian woods. The panels were produced with nominal density of 850 kg.m-3, thickness of 15.7 mm and phenol formaldehyde adhesive. The experimental design was arranged in a factorial design, with the assessment of the effects of three species (pequiá, tachi-preto and angelim-da-mata) and two particle classifications (with and without fines). Their performance was evaluated with respect to their physical (apparent density, moisture content, water absorption and thickness swelling) and mechanical (static bending – modulus of elasticity and modulus of rupture and internal bond) properties, realized according to ABNT NBR 14810-3. The removal of fines in the production of panels generated a tendency towards increased MoR, MoE and internal bond values and contributed to reductions in AAw2h, AAw24h and ST2h.
