Production of fiberboard using palmyra fruit fiber as reinforcement and tapioca starch as binder is an innovation of this product. Therefore, the objective of this research was to study the effect of palmyra fruit fiber and tapioca starch contents on mechanical and physical properties of fiberboard. The materials were manufactured into sample fiberboards using a hot compression machine with temperature 190 oC, pressure 13.8 MPa and time 30 min. According to the results, addition of palmyra fruit fiber 7% resulted in internal bond strength, modulus of rupture and modulus of elasticity increased clearly. However, the increasing additions of palmyra fruit fiber reduced water absorption slowly. Furthermore, an increase of tapioca starch contents in fiberboard resulted in internal bond strength and water absorption decreased; however, modulus of rupture and modulus of elasticity significantly increased with tapioca starch contents.
