New Insight into Wood Damage Mechanisms
Snapshot: Wood fails because bad things start to happen when wood gets wet. Dimensional stability, mold growth, fungal attack, fastener corrosion, all are caused by fluctuations in moisture or an abundance of moisture in the wood. This research presents a new theory to explain the microphysical processes that happen in the wet wood which lead to the onset of these damage mechanisms.
The ability of chemicals to move in cell walls enables fastener corrosion and decay to occur. Stan Lebow, USDA Forest Service
