This study investigated the physical, mechanical and machining properties of Bamboo Hybrid Laminate Boards (BHLB) in various directions of fiber as a structural material replacing wood. The material used is dry bamboo (Gigantochloa apus) is processed into thin strips with a thickness of 4 mm and falcata veneer (Paraserianthes falcataria). BHLB were arranged using fiber direction (perpendicular and parallel) in cold pressing (30 minutes; 22.22 kgf/cm2) and hot pressing (6 minutes; 15 kg/cm2). The adhesive used is urea-formaldehyde (UF) resin (glue spread rate of 250 g/m2 and inter veneer 170 g/m2). Physical and mechanical properties were observed to validate the feasibility of BHLB from bamboo strips and falcata veneers. The results showed that the arrangement of the fiber direction affects dimensional stability, MOE, MOR, shear strength, and screw withdrawal strength. The core of board material with falcata veneer makes lower density, low dimensional stability, and higher water absorption but the mechanical properties are not much different and have occupies the standard as a structural use. The use of bamboo strips as face and back is obtained free from machining defects. It was concluded from the results that bamboo strip can be used for making composite BHLB. Furthermore, the test results clearly show that BHLB can be used as an alternative to wood-based composites for structural use.
