Abstract

Aethiopum is a species of Borassus that is often seen in tropical Africa and has long been used for the construction of beams and poles. The buildings were never bent or damaged as a result of a termite attack. But as it became difficult to use this wood, it was abandoned. This study on wood observes closely its mechanical behavior in flexion and traction. Three-points bending and tensile tries were carried out in the longitudinal direction of the fibers on the samples. Borassus is basically made of intertwined fibers, making it a very elastic material. The packed structure of the fibers gives this wood a good resistance to bending and makes it strong in slab. The high compressive strength makes it possible to use wood as a post. Since wood is a living material, this work presents the range of the Borassus Young\'s modulus determined by experiments. The slope method used compares the behavior of the material according to two different incentives. Values were established by an Excel spreadsheet. The Young\'s modulus in tension is 16571 ± 1832 MPa, the modulus of elasticity in flexion is 23565.25 ± 3724 MPa. This article aims to contribute to the valorization of a traditional famous wood because of its natural virtues. In view of these results, we can say that Borassus is resistant to bending bite in traction.
