Assessment of Physical and Mechanical Properties Considering the Stem Height and Cross-Section of Paulownia tomentosa (Thunb.) Steud. x elongata (S.Y.Hu) Wood

The aim of this study is to analyze the properties Paulownia tomentosa x elongata plantation wood from Serbia, considering influence stem height (0 1 m and 4.5 6 above soil level—height spot) radial position pith bark (in core, near bark, in between these zones—cross-section spot). results show that most are improved when samples were taken upper parts tree (height spot (cross-section mean density measured 275 kg/m3 at 4.5–6 245 for collected 0–1 trunk height. had highest value on (290 kg/m3), mature a m, 230 kg/m3. Brinell hardness exhibited values axial direction (23 N/mm2) (28 N/mm2). bending strength was 41 N/mm2 trunk’s range 45 cross-section, close cambium. three-point modulus elasticity (MOR) up 5000 N/mm2, MOR 5250 N/mm2. Regarding compressive strength, pith, with 23 (4.5–6 m), whilst it 19 bark. tensile was, average, 40 both levels 49 pith. screw withdrawal resistance 58 N/mm extracted 92 specimens This stresses influence, short-rotation timber, indicators, such as juvenile (difference emphasized after fifth year growth) variation, physical mechanical sawn wood. will help utilize more efficient sustainable resources, fast-growing hardwood species Europe adequate core material sandwich applications furniture, transport, sport articles, lightweight composites, being considered European Balsa.
