Effectiveness of Asymmetrical Veneering with Hardwood Species of Varying Shrinkage and Porosity

Abstract

The aim of the study was to check deformations of asymmetrically veneered panels using glue with elastic bonding. In order to achieve the aim, a special stand was designed to analyse the geometry of furniture elements. It is known that boards became convex after veneering with rigid glue. However, the level of deformations for varying parameters of veneering was not equal. As the result of veneering with elastic glue, the boards preserved their primary shape. In any case, the level of deformation depended on wood veneer species. The deformation of the boards was not influenced by their shrinkage. It is supposed that the main influence is the difference in porosity.
