This article presents the results of a study that assessed bending quality and that determined the minimum radius of bending curvature of eight plantation and regrowth Australian timbers using the microwave wood bending process: <i>Eucalyptus nitens</i>, <i>Eucalyptus saligna</i>, <i>Eucalyptus marginata</i>, <i>Eucalyptus diversicolor</i>, <i>Pinus radiata</i>, <i>Nothofagus cunninghamii</i>, <i>Atherosperma moschatum</i>, and <i>Acacia melanoxylon</i>. Based on the results of the study, the microwave bending performance of the wood species was rated as follows: (1) <i>E. diversicolor</i>, very good (sanding or small amount of machining was required); (2) <i>P. radiata</i>, <i>Atherosperma moschatum</i>, and <i>E. nitens</i>, decent (machining was needed); (3) <i>Acacia melanoxylon</i> and <i>N. cunninghamii</i>, satisfactory (fairly large failures occurred but these were removed by machining); and (4) <i>E. saligna</i> and <i>E. marginata</i>, very bad (large failures which could not be removed by machining). Overall, the results of the study on the bending performance capabilities of plantation and regrowth Australian timbers showed several differences compared with the literature data relating to the bending abilities of the relevant old growth timbers. 收起
