Description

Abstract Most of the furniture manufactured in Australia is made from the eucalypt timber species. Although in the past old-growth eucalypt timbers were primarily used for the production of furniture and other appearance products, a global trend to promote the sustainable use of timber resources has stimulated the industry to adapt to the change by utilizing plantation and regrowth timbers. Reference materials on the properties of Australian species provide data on old-growth timbers but limited publications are available which compare the properties of plantation and old-growth timbers for high-value wood products. So, a research study was undertaken with the goal of investigating the suitability of seven plantation-grown Australian hardwoods for furniture (15 to 40 years of age of harvest). Selected properties of the timbers (density, modulus of elasticity [MOE], and modulus of rupture [MOR]) were assessed and compared with the data on old-growth timber of each species. The results of the study showed that the densities of young plantation timbers were not much lower than those of old-growth wood. The ratio of plantation to old-growth wood varied between 0.82 (for 18-year-old Corymbia maculata) and 0.99 (for 40-year-old Eucalyptus cladocalyx). The ratio of plantation to old-growth wood for MOE and MOR varied between the species as well as between the age of the trees. It was concluded that special care should be taken when using young plantation timbers for furniture production. Although 15-year-old timbers could be confidently used for non-structural appearance components of furniture, they should not be considered as reliable engineering material for structural components of furniture due to the high variability of their engineering properties.
