Abstract

The main objective of this research was to determine the fibre saturation point of tropical wood. Two different methods were used to achieve this aim: the logarithm of strength properties versus moisture content and volumetric shrinkage-moisture content plot to zero shrinkage. The test included selected wood species from Africa: Opepe, Iroko, African padouk, and Wenge, and South America: American mahogony and Ipe. For comparison, selected domestic wood species of a similar structure – European beech (Fagus sylvatica L.) – were also tested. Determination of the fibre saturation point of the selected wood species using two methods delivered similar results (the small differences were not significant). The results showed that, generally, the fibre saturation point of the tropical wood species was lower than in the case of the European wood species. The lowest values of the fibre saturation point were shown by the African padouk and Ipe (approx. 17 %). Moreover, it was found that in the case of the tropical wood, the basic density had a significant influence on the sorption properties of the tested wood species.

用不同方法测定选定热带树种纤维饱和点

本研究的主要目的是确定热带木材的纤维饱和点。采用了两种不同的方法来实现这一目标:强度性能与含水率的对数和体积收缩-含水率图至零收缩。测试包括来自非洲的木材品种:奥佩、伊罗科、非洲帕多克和文格，以及南美洲的美洲红木和伊布。为了进行比较，还对结构相似的国内木材种欧洲山毛榉(Fagus sylvatica L.)进行了测试。用两种方法测定所选树种的纤维饱和点的结果相似(差异不大)。结果表明，热带树种的纤维饱和点一般低于欧洲树种。纤维饱和点的最低值是非洲的padouk和Ipe(约为1。17%)。此外，还发现在热带木材的情况下，基本密度对被试木材的吸附性能有显著影响。
