Delamination in Timber Induced by Drying

Author
  1. 1.
Chapter

Abstract

In the context of wood drying, delamination can be regarded as a defect due to poor drying where separation between wood fiber cells occurs on surface (surface checks) or inside of wooden boards (internal checks) and in the form of splits (i.e. end split) at the end of the timber board. Solid wooden board can be considered as naturally laminated product. Before discussing delamination aspect of wood fibers during drying in further detail, it is helpful to discuss about basic principles and purpose of wood drying.
