Abstract:

We used a experimental procedure of wood drying to show the nature of the pore space in wood. Cubic blocks of Ginkgo biloba and Castanea mollissima wood were executed, and posting them in oven, the temperature was increased after 4 hours and measured the mass changes of weight and volume at the same time, the plots of the mass versus block edge sizes are straight lines whose slopes correspond to the fractal dimensions of the void volume in the wood. Results for different species and for distinct temperature are shown. Suggesting the fractal dimension as a new relvant to parameter to characterize the porosity of wood.

Key words: Wood, Drying, Porosity, Fractal
