In India, furniture, paper, pulp and panel product industries which are wood based are facing acute shortage of conventional timber. The remedy lies in the use of non-conventional secondary species for different end uses. For furniture, construction and sports goods manufacture, a large number of secondary and tertiary species have been considered considered of which Hevea brasiliensis(rubbe wood) is one. About 1.3 million cu.m of rubber wood is available annually from spent rubber wood in the country. It is seen from the data available that a large quantity of rubber wood is coming into the market and this volume of wood has to be rationally utilised. Earlier workers during their studies on the physical and mechanical properties of rubber wood, based their recommendations solely on experiments using selective and representative samples, the results of which cannot be used for purpose of comparison. Rubber wood is widely used for manufacture of packing cases, match splints and furniture but these are not based on standard tests. Also it would appear that rubber wood can be put to more cost effective uses. With the above objectives in view, a detailed study on the strength properties of plantation grown rubber wood was undertaken. Wood from eight trees of Hevea brasiliensis of about 30 years age(average height 10 m and girth 0.9 m) were procured from Sullia region, South Kanara, Karnataka. Specimens prepared from such logs were tested for static bending, compression perpendicular and parallel to grain, screw and nail holding power, hardness, shear tension, shrinkage and specific gravity. Based on the data collected, timber is classified as heavy, moderately strong, not tough, steady and hard. The study also reveals that the timber is dimensionally stable owing to its low shrinkage value.
