Resumo: | This work aimed to evaluate the physical-mechanical performance of laminated veneer lumber (LV) produced withdifferent compositions of tropical Amazonian species and Pinus oocarpa. Three tropical species were used: Cordia goeldiana Huber. (Freijó), Parkia gigantocarpa Ducke (Faveira) and Brosimum parinarioides Ducke (Amapá doce). For comparison, Pinus oocarpa wood obtained from an experimental stand was used. Three types of veneer combination were evaluated: (i) one species; (ii) the three Amazonian species combination and (iii) combination of Amazonian species with Pinus oocarpa. The acoustic propagation velocity was also evaluated with the stress wave timer for correlation between dynamic modulus of elasticity (MOEd) and static modulus of elasticity (MOEs) of the panel. Panels produced with Amazonian species presented lower water absorption than Pinus oocarpa panels. Regarding the mechanical properties, the lowest strength was verified for “faveira” panels. There was no statistical difference among panels in glue line shear strength. The stress wave timer could be used for prediction of MOEs by using MOEd. |
