Bark/wood bond, seasonal variation, chip/bark segregation


Bark/wood bond strength was determined for the following Australian grown species: Pinus radiata. Eucalyptus obliqua, and a mixture of E. viminalis and E. rubida. In addition, sixteen other variables describing tree vigor, drought stress, tree size, and material properties were measured. The experiment was conducted in three seasons. and seasonal variation of bond strength was shown for these species.

Seasonal variation in bond strength was similar to that found by other workers. The sapwood moisture content of the eucalypts had a low variability over the seasons. Correlations were found between bond strength and the material variables for the pines sampled in summer and the eucalypts.
