The Palmyra petiole is the biovégétal material widely used in Chad for the artisanal manufacture of furniture and other works. The present study deals with the determination of its physical, chemical and mechanical characteristics. We carried out the chemical analyzes, the physical tests and the mechanical tests in three points flexion, in traction and in compression.
The results of our physicochemical analyzes and mechanical tests are satisfactory.
Its cellulose, lignin and hemicellulose contents obtained justify its resistance to physical and chemical degradation and its attack by termites.
The values of its mechanical characteristics obtained place it between the category D50 and D60 of hardwoods.
Those of its physical properties place it among the light woods.
This study, the first on the knowledge of the scientific and technical properties on Chad's petiole of palmyra, opens perspectives on a new field of study on the behaviour of this abundant natural raw material.
