摘要：

In this research, five groups of compressed wood specimens were investigated, four made from compressed Japanese cedar (Cryptomeria japonica D. Don) with compression ratios (CR) of 33%, 50%, 67% and 70%, and one without compressing for control purpose. The measurements of moisture-dependent swelling of the specimens were carried out in the R, T and L directions, with typical strain values of 10%, 1.5% and 0.1% respectively corresponding to the CR = 67%. Mechanical property tests of the compressed wood were also undertaken. Material properties obtained cover radial and tangential swelling strain rates, shear moduli in LR. LT and RT planes, Young's moduli in the L, R, T directions and Poisson ratios in all planes. The Young's moduli along the longitudinal and radial directions have been increased by over 300% in relation to the CR of 70%. (C) 2010 Elsevier Ltd. All rights reserved.
