13. PARTICLEBOARD PRODUCTION WITH RESIDUES FROM MECHANICAL PROCESSING OF AMAZONIAN WOODS
RESUMO A falta de aproveitamento dos resíduos gerados pelo processamento mecânico da madeira e seu descarte inadequado são desafios para a indústria madeireira. Esses poderiam ser utilizados em produtos de maior valor agregado. O objetivo deste trabalho foi avaliar a utilização de resíduos gerados pelo processamento mecânico das madeiras amazônicas

14. Mechanical tests on Corymbia citriodora battenboard panels coated and reinforced with giant bamboo veneers
RESUMO Painéis sarrafeados de madeira densa geralmente rompem na linha de cola, ao serem carregados. Objetivou-se mostrar que lâminas finas obtidas de colmos maduros de Dendrocalamus asper, por meio de torneamento mecânico, são apropriadas para revestir e reforçar tanto a madeira de eucalipto processada, com pequenas espessuras, como painéis sarrafeado

15. Painéis de partículas elaborados do mesocarpo do dendê como alternativa ao MDF utilizado na construção civil
RESUMO A escassez dos recursos florestais integrada à necessidade de aquisição de produtos mais ecológicos demanda o uso de outros tipos de biomassa, além da madeira no setor construtivo. Diante disso, o mesocarpo do dendê - resíduo oriundo da agroindústria e com grande potencial de utilização para desenvolvimento de novos materiais - surge como al

18. Evaluating the Effects of Removing Fines from Particleboards Manufactured from Amazonian Wood Residue
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 densi

19. Technological Feasibility of Hovenia dulcis thunb. Species for the Production of Edge Glued Panels
ABSTRACT This study aims to evaluate the use of Hovenia dulcis wood to produce Edge Glued Panels – EGP. To this end, joints with dimensions of 5.0 × 31.0 × 2.5 cm (Width × Length × Thickness) were put together using polyvinyl acetate (PVAc) and emulsion polymer isocyanate (EPI) adhesives at a spread rate of 200 g.m-2 and the chemical characterization

20. ANALYSIS OF ELASTICITY IN WOODS SUBMITTED TO THE STATIC BENDING TEST USING THE PARTICLE IMAGE VELOCIMETRY (PIV) TECHNIQUE
ABSTRACT The most important parameter in terms of material mechanical behavior knowledge is the modulus of elasticity, being traditionally obtained through destructive tests. The objective of this study is the verification of the potential use of the particle image velocimetry technique (PIV) as a tool to obtain the modulus of elasticity in sawed wood sample

22. Particleboard Panels Produced with Different Radial Positions of Pinus oocarpa Wood
ABSTRACT The aim of this study was to evaluate the effect of different radial regions of Pinus oocarpa wood on the physical and mechanical properties of particleboard panels. Three different radial regions (internal, intermediate and external) and the mixture (integral log) were assessed. Experimental panels were produced with a nominal density of 0.70 g/cm3

23. Hybrid Sandwich Particleboard Made with Sugarcane, Pínus Taeda Thermally Treated and Malva Fibre from Amazon
A multilayer particleboard panels, consisted of sugarcane bagasse reinforced composite as core material and hybrid composites made with Pinus taeda particles and Malva fibres as facing materials, were designed and evaluated in this work. Tukey test was used to identify the effect of the facing material, considering different combinations of Pinus taeda parti

24. The Effect of Post-Heat Treatment in MDF Panels
This study was to evaluate the effect of post-heat treatment on the physical and mechanical properties of MDF (Medium Density Fiberboard) panels. Commercial MDF panels were produced in Brazil using Pinus wood and urea-formaldehyde (UF) adhesive. The post-heat treatments were carried in a factorial 3 x 2 (three temperatures of heat treatment - 200, 225 and 25
