ENGREF-FCAP “Flying Wood’’ Method to Characterize Unknown Central Africa Tropical Woods Relative of Their Drying

When we want to opposite excessive exploitation of some species of wood in the tropics, it is important to characterize unknown woods with intention of their valorization. This is most urgent than in the majority of these countries, only some species are highly exploited and the species less valorized are destroyed during the researches of known species in the forests. ENGREF-FCAP ‘’flying wood’’ method is an alternative to classify unknown woods according to their drying. This method permits us to evaluate deformations of wood sample during a dissymmetrical drying and to estimate also evolution of their drying kinetic. The radius of the curvature of samples and drying kinetic permit us to compare the attacks of the drying air conditions on the samples. When these attacks are capable to destroy the quality of wood, a review of these conditions permits to want favorable conditions until we obtained the drying table of unknown woods.
