High-Quality Particleboard from Cross-Grain, Knife-Planed Hardwood Flakes

A factorial experimental design was used to study the effect of four hardwood species, three panel densities, and three cross-grain flake thicknesses on particleboard strength and dimensional properties, flake geometries, and species- particleboard density relationships. Cross-grain knife planed surface, defects were less than 1/64 inch. Regression equations were developed to predict bending and internal bond strengths from species and particleboard densities. Linear expansion for all species was less than 0.18 percent for all species and less than 0.12 percent for basswood and yellow-poplar with a 30-90 percent relative humidity change. The panels from cross-grain knife-planed flakes exceeded commercial standards for board types at the densities tested.
