An Innovative Method for Determining Moisture Gradient of Wood Products
Snapshot: Changes in moisture content of wood-based composite materials can lead to linear expansion and, more specifically, hygroexpansion. This can cause severe internal stresses resulting in deformities and defects such as warping, surface checks, and honeycomb during the wood drying process. A non-destructive method of measuring moisture content across a dimension of hygroexpansive composite material using radiation and volumetric shrinkage correction has been invented to create a profile of moisture content changes over time.
