Abstract:
This work deals with the study of physical-mechanical behaviour of Monopetalanthus (Andoung), a biomass specie from Gabonese forest, under natural moistening and drying phases. Wood, which is generally used for the conception of footbridges in Gabon and therefore exposed to the weather conditions. Some pieces of this specie have been sized following its radial and tangential plane. In the first, the section of each specimen has been analysed by using a scanning electron microscope, to get maps of the internal arrangement of cells of this specie according to the radial – Tangential (RT) and Tangential – Longitudinal (TL) axis planes. Then physical tests (drying and moistening) have been achieved, using specimens in a room where condition of temperature T (°C) and pressure p (mmHg) are considered constant. The principal parameters followed during the tests are: (i) the dimensions of the radiale plane (R, T).(b, h), and (ii) the weight of each specimen studied. The results show a link between the variations of water in the specimen and its geometrical parameters. Specifically, a pronounced effect of drying and moistening on its dimensional variations before the Fiber Saturation Point (FSP) is attested. This work is the beginning of a series of studies conducted on several species endemic to the Gabonese forest, with the scope to demonstrate and prove their possible use in structures. The goal is to provide a database of the intrinsic characteristics of a specie from Gabonese forest, to make possible their use for a better structural design of structures based on specific species of wood.
