Evaluating the warping of laminated particleboard panels

Abstract

Laminated wood composites have been used widely in the secondary manufacturing processes in the wood panel industries. Warping, which is defined as the out-of-plane deformation of an initially flat panel, is a longstanding problem associated with the use of laminated wood composites. The mechanism of warping is still not fully understood. A new two- dimensional warping model based on mechanics of layered composites was introduced to simulate the warping behavior of laminated wood composites. Actual warping performances of veneered particleboard panels under different relative humidity environments were tested and compared with the predicted warping performances based on the two-dimensional warping model. The result indicted that the new warping model could be used to simulate the warping behavior of layered wood-based composites.
