Compressive Creep of Wood under High Temperature Steam
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.
