Kavisli Ahşap Lamine Elemanlarda Biçim (Form) Kararlılığı Performansının Belirlenmesi

Bu çalışmada, vakumlu membran preste üretilmiş kavisli ahşap lamine elemanların biçim (form) kararlılığı performanslarının belirlenmesi amaçlanmıştır. Bu amaca uygun olarak 1,5 mm kalınlığında Doğu kayını (Fagus orientalis Lipsky), sapsız meşe (Quercus petrean Lieble) ve sarıçam (Pinus sylvestris) papel kaplamalar, PVAc dispersiyonu D4 tutkalı ile vakumlu membran preste yapıştırılarak 13 katmandan oluşan kavisli lamine ahşap örnekler hazırlanmıştır. Hazırlanan numunelere diyagonal basma direnci deneyi uygulanmıştır. Sonuç olarak, diyagonal basınç direnci en yüksek kayın laminasyonda çıkarken meşe laminasyon ile arasındaki fark istatistiksel olarak önemsiz çıkmıştır. En düşük direnç değerini sarıçam laminasyon örnekler vermiştir. © Afyon Kocatepe Üniversitesi

Determination Of Form (Shape) Stability Performance On Curved Laminated Wood (Lvl) Elements

The following determines performance stability of curved laminated wood elements made with a vacuum membrane press. For this purpose, 13 layers of 1.5 mm thick beech (Fagus orientalis Lipsky), sessile oak (Quercus petrean Liebl) and pine (Pinus sylvestris) veneer layers were glued with D4 adhesive using a vacuum membrane press and curved laminated wood samples were prepared. Diagonal compression test was applied on the prepared samples. The highest diagonal compression strength difference found between beech laminate and oak laminate was statistically insignificant. Most low strength samples consisted of laminated pine
