Abstract

In this study, fiberboards with a specific gravity ranging from 0.2 to 0.5 were made using acetylated, steam-treated, and untreated fiber. In all boards, dimensional stability increased as specific gravity decreased from 0.5 to 0.2. Fiberboards made from acetylated fiber were more dimensionally stable than boards made from steam-treated fiber at all specific gravity levels tested. Steam-treated fiberboards resulted in a 15% weight loss of hemicelluloses and some loss of lignin and extractives. Boards with a specific gravity of 0.2 had a low modulus value, which was probably due to poor adhesion between fibers.
