Analysis of the Physical-Hydrical Behavior of Massouhoin Coconut Tree Wood in Togo

Abstract

Wood is a very complex and anisotropic material whose properties are significantly influenced by its age and plantation areas. The purpose of this study is to determine the density distribution model of COCOS NUCIFERA (coconut tree) wood from Togo and to analyze its water behavior of physical and water properties 932 wood specimens are selected from a tree trunk from the locality of Massouhoin in Togo. These specimens were subjected to density and water absorption tests. The average density and absorption rate are respectively 0.372 and 44.95%. The average longitudinal swelling rate is 2.444 and 10.333% for radial swelling. The densities, absorption, and swelling rates of wood vary according to a polynomial law of degree two in the radial directions (from the periphery to the center) and longitudinal directions (from the base to the top of the trunk). Models are set up to deduce the properties (density, absorption, and swelling) in the different parts of the coconut tree trunk. The actors of the use of timber and service thus have models allowing them to deduce the properties of the wood for decision-making on the possible destinations of coconut tree wood according to the different parts of the trunk.
