Utilization of Bamboo as Lightweight Sandwich Panels
Keywords:bamboo face, bamboo density, node of bamboo, physical and mechanical properties, lightweight panels
Lightweight sandwich panels consisting of bamboo faces and oil palm trunk core were manufactured using melamine urea formaldehyde with the resin content of 250 g/m2 (solid basis). The parameters examined were node and density of bamboo faces. Physical (board density, thickness swelling and water absorption) and mechanical (modulus of elasticity and modulus of rupture) properties of the sandwich board obtained were investigated and compared with other bamboo products and commercial wood based products. Result showed that this panel had better dimensional stability than those of other bamboo products but lower bending strength. Node of bamboo had no significant effect on any board properties examined. Most of board properties were influenced by bamboo face density. Comparing the properties to commercial wood based products, this panel could be used as wall/floor applications.
