Influence of Veneer Density on Plywood Thickness and Some Mechanical Properties [PDF]

Rural Sustainability Research, 2021
Abstract It has been common knowledge that as the density of wood increases, the mechanical properties also improve. In turn, the density of wood depends on many factors, including the wood moisture content, location and cross-section in the trunk, the type of treatment and the parameters of technological processes.

Heat treatment of poplar plywood: modifications in physical, mechanical and durability properties

iForest - Biogeosciences and Forestry, 2023
Plywood made of poplar are limited to indoor usages since poplar exhibits a rather low natural durability. Recently, wood heat treatments have been applied to improve properties such as decay susceptibility and dimensional stability. This study examines the potential of exposing poplar plywood to heat treatment to extend the potential of applications ...
