The forest raw material base of Ukraine needs a long-term recovery, caused by current shortage of wood and in the long-term perspective, as well. One of the ways to solve this problem is to create plantations of Paulownia tomentosa (Thunb.) Steud., which are able to accumulate in a very short time a significant stock of wood, suitable for industrial use. Determination of the physical and mechanical properties was carried out on samples of standard sizes. It has been established that the density of paulownia wood, grown under the conditions of the Western Forest Steppe of Ukraine, ranges from 329–342 kg·m-3 (sapwood, heartwood) to 416 kg·m-3 (middle part between the sapwood and heartwood). Under the conditions when only air moisture influences the wood, the moisture content increases up to 12.9 %. Static bending strength, compressive strength parallel to grain, static hardness, modulus of elasticity of sapwood and heartwood parts of the trunk are characterized by minimum values, and the middle part (between the sapwood and heartwood) – by maximum ones. Therefore, in terms of appearance and texture, the wood has the most similarity with the wood of common ash; considering its density value, paulownia wood resembles the wood of Norway spruce and silver fir, but due to lower moisture absorption and the content of tannins, it is more resistant to decay than the mentioned species; the middle part according to some mechanical indicators is close to common pine wood, therefore, it can be widely used in building industry. Paulownia tomentosa wood is advisable to be used as a promising material for the production of firewood and wood pellets. The data we have obtained can be taken into account by specialists in the woodworking, furniture and agricultural industries when planning the creation of plantations and the use of its wood.
