In this study, the effects of spiral grain on some physical properties of the Calabrian pine (Pinus brutia Ten.) wood were investigated. For this purpose, 17 sample trees with various spiral grain angles, were taken from the Çakirlar region, Antalya district. The selected trees were divided into five groups according to grain angles. Tests were carried out for oven dry density, density values in volume, shrinkage, fiber saturated point (FSP) and maximal moisture content. The results led to a number of conclusions; In general, density increased in relation to the spiral grain increase. Density (oven dry weight/green volume) increased after …

The effects of spiral grain on some mechanical properties of Calabrian pine wood were studied. For this purpose, 17 sample trees were taken from Çakirlar region, Antalya district. The experimental trees were classifed into five groups according to the values of spiral grain angles as follows: 0- 5 % , 5-10 % , 10-15 %, 15-20 %, and > 20 %. No difference was found in bending strength and modulus of elasticity, up to 10 and 15 % spiral grain degrees, respectively. A spiral grain of 20 % or higher can be permitted in compression stresses. If wood has a spiral …
