Mechanical Caracteristics of Fiber Palmyra

Abstract

We are interested in this work to the determination of the mechanical features of the fibre of a male Palmyra (Borassus aethiopum. Mart) aged around 40 years, taken in Houndouma, a village at the southern of Djam#xE9;na in Chad. The paper presents results of an experimentation achieved on fiber's sapwood and heartwood's fiber. Sapwood and heartwood constitute the part useful of the log of the Palmyra as material of laths and frameworks in the traditional and semimodern habitat construction in Chad. Tests of traction achieved to the laboratory of institute French of the Advanced Mechanics permitted to determine the elastic modulus, rupture stress and rupture deformation of the fibers extracted from the heartwood and the sapwood. The knowledge of the mechanical features of these fibers opens a perspective of the survey of their utilization as reinforcement in artificial composite materials.
