ABSTRACT
Cell recovery of densified wood the strain energy stored during the densification is proportional to the transverse deformation. the cell walls of earlywood, which are deformed to a larger extent as opposed to those of the latewood cells are the first to regain their initial shape under the effect of humidity and temperature. normally the earlywood recovers first, before the latewood cells. However, the recovery of the sample never reaches 100%,
since the components of the middle lamella of the compound, which were replaced (dislocated) during the densification, prevent the cells from finding exactly their initial forms (figure 6.34). if the densification is carried out in the radial direction, the woody rays may undergo irreversible plastic deformation (figure 5.13b and 6.34). in the best case scenario, when the reconditioning was carried out in the tHm reactor at the same temperature (110 °C) and with the same relative humidity (rH = 100%) of the densification, the recovery was about 88.5%.
