Aim of study: This study aimed to evaluate the bonding, mechanical, physical and finishing performance of 3-layer plybamboo.
Area of study: The study was conducted under laboratory conditions using bamboo culms harvested from FRIM, Malaysia.
Material and method: Two Malaysian bamboo species; Gigantochloa levis (beting) and Gigantochloa scortechinii (semantan) were used to fabricate the plybamboo. Urea-formaldehyde (UF) adhesive was used as the bonding medium.
Main results: The results showed that the shear bond strength of plybamboo from G. scortechinii was greater than G. levis when tested in dry condition, but was inversed when tested after the 24 hours’ water immersion test. The modulus of rupture (MOR) and modulus of elasticity (MOE) of plybamboo from G. levis and G. scortechinii were 103.43, 14001 N/mm2 and 123.56, 18703 N/mm2, while the compression-shear strength was 47.97 and 53.16 N/mm2 respectively. Meanwhile, plybamboo made from G. scortechinii had higher thickness swelling (9.68%), linear expansion perpendicular to grain (1.13%) and water absorption (26.51%) than those from G. levis. The finishing performance of plybamboo from both species ranges from moderate to good.
Research highlights: Generally, the plybamboo produced from G. scortechinii using UF resin showed better shear bond strength, mechanical, physical and finishing performance compared to G. levis.

Çalışmanın amacı: Bu çalışmanın amacı, 3 katmanlı plybamboo’nun yapışma, mekanik, fiziksel ve yüzey bitirme performansını değerlendirmektir.
Çalışma alanı: Araştırma, FRIM’den temin edilen bambu materyali kullanılarak laboratuvar koşullarında yürütülmüştür.
Materyal ve yöntem: Plybamboo üretiminde iki Malezya bambu türü, Gigantochloa levis (beting) ve Gigantochloa scortechinii (semantan), kullanılmıştır. Bağlayıcı madde olarak üre-formaldehit (UF) tutkalı kullanılmıştır.
Temel sonuçlar: Kuru koşullarda G. scortechinii’den elde edilen plybamboo’nun yapışma kayma direncinin G. levis’e göre daha yüksek olduğunu, ancak 24 saatlik suya daldırma testinden sonra bu durumun tersine döndüğünü göstermiştir. G. levis ve G. scortechinii’den üretilen plybamboo’nun MOR ve MOE değerleri sırasıyla 103.43 ve 14001 N/mm² ile 123.56 ve 18703 N/mm², basınç-kayma direnci değerleri ise 47.97 ve 53.16 N/mm² olarak belirlenmiştir. Ayrıca, G. scortechinii’den üretilen plybamboo’nun kalınlık artışı, liflere dik doğrultudaki doğrusal genişleme ve su alma oranı daha yüksek bulunmuştur. Her iki türden elde edilen plybamboo’nun yüzey bitirme performansının orta ile iyi arasında değiştiği saptanmıştır.
Araştırma vurguları: Genel olarak, UF reçinesi kullanılarak G. scortechinii’den üretilen plybamboo’nun, G. levis’ten üretilene kıyasla yapışma kayma direnci, mekanik, fiziksel ve yüzey bitirme performansı bakımından daha iyi sonuçlar verdiği belirlenmiştir.
