Abstract

cak, Turkey were determined. Mechanical properties, such as modulus of rupture, modulus of elasticity,

impact bending strength, tension strength (perpendicular and parallel to grain), compression strength, shear

strength, and static hardness were measured. According to the test results the sapwood samples provided better

mechanical properties than the heartwood samples. It can be concluded that the lower mechanical properties of

the heartwood samples were due to the presence of high proportion of juvenile wood in the heartwood.

Türkiye, Karabucak’ta Yetişen Okaliptüs Grandis’in Öz Odun ve Diri Odununun Mekanik Özellikleri

Abstract

Bu çalışmada, Türkiye-Karabucak’ta yetişen Okaliptüs grandis’in öz odun ve diri odununun bazı mekanik özellikleri belirlenmiştir. Eğilme direnci, elastikiyet modülü, dinamik eğilme direnci, liflere paralel ve liflere dik çekme direnci, basınç direnci, makaslama direnci ve statik sertlik ölçülmüştür. Test sonuçlarına göre; diri odun örnekleri öz odun örneklerinden daha iyi mekanik özellikler vermiştir. Öz odun örneklerinin mekanik özelliklerinin düşük olması, öz odun bölgesinde genç odunun yüksek miktarda bulunmasından kaynaklandığı söylenebilir.

Keywords
