• Abstract:

  The work aimed to evaluate the physical and mechanical properties of plywood panels produced with Cecropia hololeuca and Pinus elliottii, in different compositions of blades, phenol-formaldehyde rhein was used, with a solids content of the beat of 35%, weight of 160 g/cm³ in a single line, in the pressing cycle a pressure of 12 kgf/cm² and a temperature of 140 °C for 10 min. Based on the recommendations of ABNT standards, physical-mechanical tests of apparent specific mass were performed; water absorption; swelling in thickness; swelling plus recovery in thickness; moisture content, static bending and shear in the glue line. The panels produced showed physical-mechanical properties in accordance with the parameters defined by ABIMCI and ABNT. Some results obtained significant differences, with emphasis on the panels with pine veneers and those combined with pine on the cover.
