Abstract

In this study, determination of the edge and face dowel holding performances of some wood and wood composite materials were aimed. Turkish beech (Fagus orientalis Lipsky) and Scotch pine (Pinus sylvestris L.) were selected as the wood materials while okoume (Aucoumea klaineana) plywood (OKP), particleboard (YL), two different quality of oriented strand boards (OSB1, OSB2), medium density fiberboard (MDF), particleboard surfaced with synthetic resin sheet (SUNTALAM) and medium density fiberboard surfaced with synthetic resin sheet (MDFLAM) were used as the wood composite materials in the tests. Polyvinylacetate (PVAc) adhesive was utilized for gluing of the dowels. A total of 660 specimens were prepared for edge withdrawal tests including 9 material types (2 solid woods, 7 wood composites), 2 different diameters of dowel, 3 dowel penetrations and 10 replications for each group, and 540 specimens were prepared for face withdrawal tests, and they were tested under static loads. Furthermore, results of the tests were incorporated into predictive expressions that allow furniture designers to estimate edge and face dowel withdrawal performances for each material as a function of diameter of dowel and their depth of penetration. Results showed that the expressions developed provide reasonable estimates of edge and face dowel holding performances.

Özet

Bu çalışmada; bazı masif ve kompozit ağaç malzemelerin, kenardan ve yüzeyden kavela tutma performanslarının belirlenmesi amaçlanmıştır. Deneylerde ağaç malzemelerden Doğu kayını (Fagus orientalis Lipsky) ve sarıçam (Pinus sylvestris L.), kompozit ağaç malzemelerden ise okume (Aucoumea klaineana) kontrplak (OKP), yonga levha (YL), iki ayrı kalitede yönlendirilmiş yonga levha (OSB1, OSB2), orta yoğunlukta lif levha (MDF), sentetik reçinelerle kaplanmış yonga levha (SUNTALAM) ve lif levha (MDFLAM) kullanılmıştır. Kavelaların yapıştırılmasında polivinilasetat (PVAc) tutkalından yararlanılmıştır. 9 malzeme çeşidi (2 masif, 7 kompozit), 2 farklı kavela çapı, 3 kavela girme derinliği (etkili boyu) ve her örnekten 10 yineleme olacak şekilde toplam 660 kenardan çekme, 540 adet de yüzeyden çekme örneği hazırlanmış ve statik yük altında denenmiştir. Ayrıca, deney sonuçları sayısal formüller haline getirilerek mobilya tasarımcılarının kenardan ve yüzeyden kavela tutma performansını, her bir malzeme çeşidi için kavela çapı ve kavela etkili boyunun fonksiyonu olarak tahmin etmeleri amaçlanmıştır. Sonuçlar, elde edilen formüllerle, kenardan ve yüzeyden kavela tutma performansının mantıklı bir şekilde tahmin edilebildiğini göstermiştir.
