Compressive Creep of Wood under High Temperature Steam
-
W. Dwianto
Summary
Creep compliance curves in the radial compression were measured under steam for sugi (Cryptomeria japonica D. Don) at temperatures up to 200°C. The creep compliance curves for 30 min (I) and those with pre-steaming for 30 min (II) were well connected at 30 min when the structural changes due to the degradation of hemicelluloses or the decomposition of lignin as well as hemicelluloses occurred. However, the creep curves (I) at 30 min differed markedly from creep curves (II) when the structural changes due to the increase in regularity of crystalline lattice spacing of the microfibrils or the formation of cross-linkages between the cell wall polymers occurred. It was concluded that two kinds of structural changes could be detected well by creep measurement.
