Abstract
Kontrplak üretiminde yaygın olarak kullanılan Doğu Kayını (Fagus orientalis Lipsky) ve Titrek Kavak (Populus tiremula) odunlarından elde edilen 1.2 mm kalınlıktaki soyma kaplama levhalarına ısıl işlem uygulandıktan sonra 3 tabakalı kontrplak üretilmiştir. İki ağaç türü ve iki farklı tutkal kullanılarak üretilen kontrplak levhalarının çekme-makaslama direnci, eğilme direnci ve elastikiyet modülü özellikleri incelenmiştir. Elde edilen sonuçlar istatistiksel olarak değerlendirilmiştir Aynı koşullarda üretilmiş kontrol örneklerine göre değişim miktarları belirlenmiştir. Genel olarak ısıl işlem uygulanmış kontrplakların direnç özelliklerinde bir azalma meydana geldiği görülmüştür.
