1. 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

2. 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

3. Production and Characterization of Polymeric Composite Materials Using MDF Waste in Powder and Poliester Terephthalic Resin
The growing demand for panels of Medium Density Fiberboard (MDF) for manufacture of furniture produces significant quantities of waste, which is often inappropriate discarded. This paper presents the study of the characterization of a polymeric matrix composite reinforced with powdered MDF residues collected from cuts machines for furniture manufacturing. Sa

4. Some physical and mechanical properties of medium-density fiberboard made from giant bamboo
The objective of this study was to evaluate the density, density profile, water swelling and absorption, modulus of elasticity and rupture from static bending, and tensile strength of experimental medium-density fiberboards manufactured using Dendrocalamus giganteus (Munro bamboo). The fiber production was carried out through the chemo-thermo-mechanical pulp

7. Characterization and anatomical structure alterations of Eucalyptus grandis wood in three refining conditions and effect in technological properties of MDF panels / Caracterização e alterações na estrutura anatômica da madeira do Eucalyptus grandis em três condições de desfibramento e efeito nas propriedades tecnológicas de painéis MDF
Currently is evidenced a great demand of growth in eucalypts MDF panels production in relation with pinus, commonly used in the industry. The present study had the objective to characterize the morphologic components of Eucalyptus grandis wood chips in natura submitted in three different refining conditions (time, pressure and energy), named inte

9. Production and characterization of MDF using eucalyptus fibers and castor oil-based polyurethane resin
The growing popularity of wooden panels renders this market segment increasingly competitive. MDF (Medium Density Fiberboard), in particular, is widely employed for a variety of applications, including civil construction, furniture, and packaging. This paper discusses a study of MDF produced from alternative raw materials, i.e., Eucalyptus fibers and castor-

10. Mechanical and physical properties of MDF panels of different densities and resin content. / Propriedades físicas e mecânicas de painéis MDF de diferentes densidades e teores de resina.
MDF Panelboards of Pinus spp fibers were prepared in laboratorial scale, with a range of densities (550 - 750 kg/m3) and urea-formaldehyde resin content (6; 8; 10; 12 and 14 wt. %), with the purpose of evaluating their mechanical and physical properties. The effect of density and resin content and their interactions were analyzed based on panel mechanical an
