Abstract

Son yıllarda, yapıştırıcı ve laminasyon teknolojilerindeki ilerlemeler, düşük kaliteli ve dayanıksız ucuz ahşap hammaddesinden yüksek kaliteli ve değerli ürünlerin üretilmesinde önemli fırsatlar sunmuştur. Laminasyon genellikle çok katmanlı malzeme üretim yöntemini ifade eder. Bu üretim sürecinin temel hedefi, oluşturulan kompozit ürünün dayanıklılığı, stabilitesi gibi birçok özelliğini geliştirip iyileştirmektedir. Glulam olarak adlandırılan tabakalı lamine kereste, kereste liflerinin birbirine paralel olarak hazırlanıp tutkal yardımıyla birbirine yapıştırılmasıyla oluşturulan tabakalı bir kompozit malzemedir. Bu çalışmada, kestane ağacı türlerinden üretilen masif, 3 katlı ve 5 katlı glulam kirişlerin eğilme özellikleri deneysel ve sayısal olarak incelenmiştir. 5 katlı glulam kirişlerin elastisite modülü, 3 katlı kirişlerden %13,39 ve masif kirişlerden %48,31 daha yüksektir. 5 katmanlı kirişin eğilme dayanımı değeri, 3 katmanlı kirişten %24,21 ve solid kirişten %65,28 daha yüksektir. Deneysel ve sayısal analiz sonuçları arasında maksimum %2 fark vardır. Sonuçları karşılaştırıldığında sonuçların birbirine yakın olduğu görülmektedir.

Effect of Layers Number on The Bending Properties of Chestnut Glulam Beams

Abstract

In recent years, advances in adhesive and lamination technologies have offered significant opportunities in the production of high-quality and valuable products from low-quality and non-durable cheap wood raw materials. Lamination generally refers to a multilayer material production method. The main goal of this production process is to develop and improve many properties of the created composite product, such as durability and stability. Laminated timber, called glulam, is a layered composite material formed by preparing timber fibers parallel to each other and gluing them together with the help of glue. In this study, the bending properties of solid, 3-layer and 5-layer glulam beams produced from chestnut tree species were investigated experimentally and numerically. The modulus of elasticity (MOE) of 5-layer glulam beams is 13.39% higher than 3-layer beams and 48.31% higher than solid beams. The modulus of rupture (MOR) value of the 5-layer beam is 24.21% higher than the 3-layer beam and 65.28% higher than the solid beam. There is a maximum difference of 2% between the experimental and numerical analysis results. When the results are compared, it is seen that the results are close to each other.
