Abstract

Twelve commercial nominal 4 × 8 ft.2 (1,200 × 2,400 mm2) wood-based panels, Medium Density Fiberboard, Particleboard, Oriented Strand Board and Plywood, were scanned for horizontal density distribution using a high resolution and accuracy digital X-ray system. Density distribution at a size of grid cell varying from 0.5 × 0.5 to 12 × 12 in.2 (12.7 × 12.7 to 304.8 × 304.8 mm2) was analyzed based on the X-ray scanned images of the panels. Detailed density distribution characteristics of the four types of wood-based panels are presented in this research. Comparisons of density variation are carried out between different panel types and between different spatial resolutions (i.e. sizes of grid cells). Results of analysis and comparison in density distribution are presented in different forms with industrial as well as academic implications.
