Young's modulus of hemicellulose as related to moisture content

Wood Science and Technology Aims and scope Submit manuscript

Summary

The Young's modulus of hemicellulose extracted from Pinus radiata wood has been measured by an indentation method. Values obtained for the modulus varied by almost three orders of magnitude, from 8.0×109 Pa in nearly dry hemicellulose to 1.0×107 Pa in nearly saturated hemicellulose. The very low value of the modulus at high moisture contents has some interesting implications for models of the mechanical behaviour of the wood cell wall.
