Özet
In this study, samples of oriental beech (Fagus orientalis L.), hornbeam (Carpinus betulus L.), and alder (Alnus glutinosa L.) wood, which are widely used in furniture production and other sectors of the woodworking industry, were comparatively examined under different climatic conditions, and their interchangeability was investigated. For this purpose, test specimens prepared from the three wood species were subjected to tests at 20 degrees C/65%, 40 degrees C/35%, and 10 degrees C/50% temperature and relative humidity conditions, and their physical and mechanical properties were determined. As a result, among the diffuse-porous wood species examined, the density of hornbeam wood was found to be 0.76 g/cm3, while that of beech wood was 0.73 g/cm3. The bending strength was determined as 129.4 N/mm2 for hornbeam wood, with the closest value observed in beech wood at 121.2 N/mm2. Similarly, the modulus of elasticity in bending of hornbeam and beech wood was found to be at comparable levels. However, the highest impact strength was measured in beech wood at 82.4 kJ/m2, while the lowest was in hornbeam wood at 56.6 kJ/m2, with alder wood exhibiting an intermediate value of 67.3 kJ/m2. When the hardness values of the wood species were examined, it was observed that beech wood (29.2 N/mm2) and alder wood (25.1 N/mm2) exhibited similar hardness resistance. Therefore, it can be concluded that hornbeam and beech wood can be used interchangeably for load-bearing applications, whereas for applications requiring hardness and impact strength, beech and alder wood species may be preferred as substitutes for one another. Thus, when the use of one of these three wood species is required, sourcing based on availability and ease of transportation may provide an economic advantage.
