Abstract
An exploratory study was conducted to evaluate the properties of laminated-bamboo lumber, herein referred to as LBL. Quasi-flattened Moso bamboo (Phyllostachys pubescens) were laminated using a resorcinol-based adhesive to form a composite which is similar in construction to that of laminated-veneer lumber (LVL). Representative samples were tested for static bending properties, internal bond strength, and dimensional stability. The effect of initial moisture content (10 and 15 percent) and glue spread rate (220, 320 and 420 g/m 2 single glueline) on LBL properties was also analyzed. Results indicate that LBL exhibits superior strength property compared to wood-based LVL, as indicated by its higher MOR. Its MOE, however, was slightly lower. Initial MC (within 15 percent) did not have a significant effect on the mechanical properties of LBL, but it appears to have a significant effect on dimensional stability. Glue spread rate had a significant effect on both the mechanical and physical properties.
