The selected properties of laminated rattan strip from large diameter calamus manan-effect of bonding direction

The laminated rattan strip from large diameter rattan (Calamusmanan) of more than 50 mm was investigated. The commercial rattan was cut into square shape of 25 mm X 10 mm X 320 mm (W x T x L) and glued together with urea formaldehyde resin (UF) either as face to face or edge to edge bonding. Each bonding was fabricated to 2, 3 and 4 layers. The physical and mechanical properties were tested in according to Japanese Agricultural Standard (JAS) and British Standard (BS). Overall, the study found that the water absorption, thickness swelling and delimitation in either cold or hot water were not significantly different with the type on bonding and number of layer. The modulus of elasticity (MoE) and maximum load (ML) were significantly different with type of bonding, but not the modulus of rupture (MoR). The MoR and MoE were not significantly different with number of layer. The ML increased with increasing layers. Large diameter Calamusmanan can be laminated with either type of bonding or number of layer.
