EvALUATION OF ThE OSB PROPERTIES

USING TROPICAL WOOD MIxTURES

A study to evaluate the composition of oriented strand board (OSB) panels and the potential of
using a mixture of three Amazonian wood species that have been underutilised by the Brazilian
wood industry demonstrates that the studied species have potential for use in the manufacturing
of OSB panels. By Diego Lima Aguiar and Victor Hugo Pereira Moutinho, Federal University of
Western Pará (UFOPA), Geraldo Bortoletto Júnior, Ivaldo Pontes Jankowsky, Luana Candaten,
