Vapour boron treatment of wood based panels: Mechanism for effect upon impact resistance
R Hashim, R J Murphy, D J Dickinson, J Dinwoodie
Samples of medium density fibreboard, chipboard and oriented strandboard (OSB) were treated to two retentions of boric acid by a vapour phase treatment. The results of a range of mechanical tests were reported by Hashim et al. (1992, 1993) in which a small reduction in impact resistance was observed. Several investigations were carried out to study how and where this loss in impact resistance occured. Possible mechanisms for the loss in impact resistance are discussed.
