Abstract

Rapid and non-destructive determination of microhardness values for specific wood materials such as pine, poplar, and MDF laminate, which are widely used in various fields including historic buildings, artifacts, construction, home furniture, children’s playgrounds, and gardens, is crucial for assessing their quality and durability. The hardness of such wood materials is typically assessed using destructive traditional methods. Therefore, this research was conducted to determine the microhardness (HCATT) values of certain wood materials such as pine, poplar, and MDF laminate for the first time non-destructively using the Computer Aided Tap Tester (CATT) system and establishing the relationship between these HCATT values and the Brinell hardness (HB) values obtained from the literature for these materials. The HCATT values of the wood materials used in the study were determined by using the contact time between the tip of the CATT device (CATT) and the surfaces of the wood materials. Empirical equations for each wood material used in this research, representing the relationship between hardness values determined using two different hardness measurement methods, were established, including the constants (c-values). According to the results obtained from the research, the shortest contact time, with an average of 362 μs, was observed in the MDF laminate material, whereas the longest contact time, with 653 μs, was observed in the poplar material. Based on the HCATT values determined using the CATT system, the lowest hardness value was 0.34 MNm-1 in the poplar material, and the highest HCATT value was 1.10 MNm-1 in the MDF laminate material. On the other hand, the high level of correlation observed between the HB and HCATT values of the materials used in this research indicates that the non-destructive CATT system can be used instead of destructive methods for determining the microhardness values of such materials, without causing any harm to the material. CATT is expected to make a significant contribution to the relevant literature because it is both faster and more cost-effective compared to the destructive tests commonly used for microhardness measurement in materials today.

Bazı Tahta Malzemelerin Sertlik Değerlerinin Bilgisayar Destekli Vurma Testi ile Tahmini

Abstract

Tarihi binalarda, tarihi eserlerde, inşaatlarda, ev mobilyalarında, çocuklara yönelik oyun parkları ve bahçeleri gibi daha birçok alanda kullanılan çam, kavak ve MDF laminant gibi belirli ahşap malzemelerin mikrosertlik değerlerinin tahribatsız bir yöntemle kısa sürede belirlenmesi, bu malzemelerin kalite kontrolleri ve dayanıklılıklarının belirlenmesi için önemlidir. Bu tür ahşap malzemelerin sertlikleri genellikle tahribatlı geleneksel yöntemler ile gerçekleştirilmektedir. Bu nedenle bu araştırma çam, kavak ve MDF laminant gibi bazı ahşap malzemelerin mikrosertlik (HCATT) değerlerinin ilk kez tahribatsız olarak Bilgisayar Destekli Vurma Testi (BDVT) sistemi ile belirlenmesi ve bu HCATT değerleri ile bu malzemelerin literatürden alınan Brinell sertlik (HB) değerleri arasındaki ilişkinin belirlenmesi amacıyla gerçekleştirilmiştir. Araştırmada kullanılan tahta malzemelerin HCATT değerleri, BDVT cihazının (BDVTC) vurucu ucu ile tahta malzemelerin yüzeyleri arasında geçen temas süresinden yararlanılarak belirlendi. Bu araştırmada kullanılan her bir tahta malzeme için iki farklı sertlik ölçüm yöntemi ile belirlenen sertlik değerleri arasındaki ampirik eşitlikler ve bu ampirik eşitliklerin c sabiti değerleri belirlenmiştir. Araştırmadan elde edilen sonuçlara göre en kısa temas süresi ortalaması 362 μs ile MDF Laminant malzemede, en uzun temas süresi ise 653 μs ile kavak malzemede tespit edilmiştir. BDVT sistemi ile elde edilen temas süreleri kullanılarak belirlenen HCATT değerlerine göre en düşük sertlik değeri 0.34 MNm-1 ile kavak malzemede elde edilirken en yüksek HCATT değeri ise 1.10 MNm-1 ile MDF Laminant malzemede elde edilmiştir. Diğer yandan bu araştırmada kullanılan malzemelerin HB ile HCATT değerleri arasında görülen yüksek düzeydeki ilişki, bu tür malzemelerin mikrosertlik değerlerinin tespit edilmesinde malzemeye zarar vermeyen BDVT sisteminin tahribatlı yöntemlerin yerine kullanılabileceğini göstermiştir. BDVT, günümüzde yaygın bir şekilde malzemelerin mikrosertlik ölçümü için kullanılan tahribatlı testlere kıyasla hem daha hızlı hem de daha ekonomik olduğundan BDVT’nin ilgili literatüre önemli bir katkı sağlaması beklenmektedir.
