Abstract

The study was undertaken to present mainly some physical and mechanical wood properties of Mahogany (Swietenia macrophylla King.) grown in homestead forest of Bangladesh. The study was carried out following the standard test methods and comparing the finding with those of standard Chittagong Teak (Tectona grandis L.f.) reported earlier. Both the physical and mechanical properties were studied in different age classes and height positions. It has been found that the average green moisture content was 39.83%, volumetric shrinkage was 6.62% and densities in green, air-dry and oven-dry conditions were 0.53, 0.55 and 0.56 gm/cm3 respectively. The average MOE and MOR valued for air-dry and oven-dry conditions were 7712.71 and 7912.12 MPa, and 71.15 and 73.59 MPa respectively. The compression parallel to grain and perpendicular to grain in air-dry and oven-dry condition were 52.65 and 55.90 MPa, and 13.45 and 14.42 MPa respectively. The effect of age and height of the tree was significant for most of the physical and mechanical properties. Some of the properties of S. macrophylla were found relatively and reasonably lower than Chittagong Teak.
