1. STUDYING THE GRAMMAGE IN LVL PANELS GLUED WITH CASTOR OIL-BASED POLYURETHANE ADHESIVE: A POSSIBLE ALTERNATIVE TO FORMALDEHYDE RELEASING ADHESIVES.
ABSTRACT Efforts have been done in order to decrease the human dependence on petroleum materials. This idea can be applied for wood adhesives and wood products. This study proposes to evaluate laminated veneer lumber (LVL) panels of Hevea brasiliensis produced with castor oil-based polyurethane and resorcinol formaldehyde in different grammages. Six rubber t

3. DISPLACEMENT MEASUREMENT IN SAWN WOOD AND WOOD PANEL BEAMS USING PARTICLE IMAGE VELOCIMETRY
ABSTRACT Throughout their useful life structures demand monitoring to verify their conditions of use. Thus, the need arises to seek methodologies capable to evaluate displacements and deformations in structural components of buildings. The objective of this research was to evaluate the use of the particle image velocimetry (PIV) technique to analyze test spe

4. 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

5. Production and Properties of a New Wood Laminated Veneer/High-Density Polyethylene Composite Board
AbstractThe paper aimed at evaluating the feasibility and the properties of a new product which combines wood veneer and high-density polyethylene (HDPE) from post-consuming plastic bags. Three HDPE amounts were evaluated: 150g/m2, 250 g/m2 e 350 g/m2. The boards were manufactured using a single-opening hot-press under such conditions: 140ºC, for 20 minutes

7. CARACTERÍSTICAS FÍSICO-MECÂNICAS DE PAINÉIS DE LÂMINAS PARALELAS REFORÇADOS COM FIBRA DE VIDRO / PHYSICAL AND MECHANICAL CHARACTERISTICS OF LAMINATED VENEER LUMBER REINFORCED WITH FIBERGLASS
O objetivo desta pesquisa foi avaliar as propriedades físico-mecânicas de painéis de lâminas paralelas (LVL) reforçadas com camadas de fibra de vidro inpregnadas com dois tipos de matrizes. Lâminas de madeira de Pinus ellliottii com espessura de 1,5 mm foram utilizadas na fabricação dos painéis. A montagem dos painéis foi realizada em duas etapas.
