“…In the last decades, this raw material has become important for the manufacture of furniture, due to the attractive coloring and density of the material (Teoh et al, 2011). In the panel segment, rubber tree wood has been used in the production of cement-wood composites (Iwakiri et al, 2017), LVL panels (Faria et al, 2020), particulate panels (Iwakiri et al, 2018;Lamaming et al, 2020) and glued laminated timber (GLT) beams (Nadir et al, 2016;Parra-Serrano et al, 2018;Faria et al, 2019).…”

This work aimed to evaluate the physical and mechanical behavior of glued laminated timber (GLT) - glulam pieces of Hevea brasiliensis treated with chromed copper arsenate (CCA), chromed copper borate (CCB) and pyrethroid in the production of GLT. The pieces were produced using three wooden laminae with dimensions of 60 x 20 x 1200 mm, (width x thickness x length), joined with epoxy adhesive under 1.0 MPa pressure for 24h at room temperature. The rubberwood had an apparent density of 0.624 g cm-3, a value close to that of Eucalyptus grandis wood, a species traditionally used in the manufacture of GLT. Regarding the GLT parts, it was observed that the preservative treatment with CCA and CCB influenced negatively the values of the mechanical properties. For resistance modulus (MOR), a reduction of 75.44 MPa to 62.36 and 58.57 MPa was found for the parts untreated and treated with CCA and CCB, respectively. There was no statistical difference for surface treatment with pyrethroid. The photomicrographs of the glue line showed that the reduction in these values was mainly due to the penetration of preservative solutions into the wood structure (cell lumens and vessels or pores), impairing the anchoring of the adhesive.

Use of Populus deltoides wood in the Production of MDP and HDP

2021

The aimed to evaluate the properties of MDP and HDP panels, produced with pure Populus deltoides or in a mixture with Pinus taeda, together with urea-formaldehyde resin. The density and chemical properties of this wood with 8 and 12 years of age were determined, which were used for the production of panels with nominal density of 0.65 and 0.90 g.cm -3 . Water absorption and thickness swelling tests were performed after 2 and 24 hours of immersion, as well as static bending and perpendicular tensile. Populus deltoides wood was classified as low-density in both ages and presented chemical properties similar to Pinus taeda. Mechanical properties obtained for the panels produced reached the minimum requirements values established by the standards NBR 14810-2 and ANSI A208.1, demonstrating the potential use of wood species for the production of MDP and HDP panels, at both ages studied and used pure or mixed with Pinus taeda wood.
