Abstract
This study evaluated the variation of the physical and mechanical properties within coconut timber's radial position (dermal, sub-dermal, core). Properties were studied on the 55-year-old coconut palm from KAU coconut farm Vellanikkara, in Thrissur, district Kerala. The density of coconut timber at the radial positions was 862.3 kg m-3, 670.8 kg m-3 and 287.9 kg m-3, respectively, for the dermal, sub-dermal, and core positions. The average moisture content of coconut timber in the dermal, sub-dermal, and core positions was 15.7 %, 16.6 %, and 17.5 %, respectively. Compressive strength parallel to the grain at the three radial positions such as dermal, sub-dermal, and core is 32764.77 kg cm-2, 25591 kg cm-2, 7532.35 kg cm-2, respectively, and the compressive strength perpendicular to the grain was found as 46712.42 kg cm-2, 39233.3 kg cm-2, 22353.04 kg cm-2. Hardness measured at the side and ends of the dermal position is 1207.612 kg and 767.65 kg, respectively. In the sub-dermal position, 1035.7 kg and 750.88 kg, respectively. The core position is 252.34 kg and 359.31 kg, respectively.
