Abstract: The teak processing residual fiber was used as the raw material, after preliminary pulverization and mechanically ground by a colloid mill, then the biomass materials with high mechanical properties were obtained by the binderless hot-press method. The findings indicated that the original teak waste fiber was laminated by the grinding and the composite material appeared layered structure after the binderless hot-pressing. Hydroxyl groups increase the cross-linking between nanofibrillatedcellulose, increase the contact area of surface hydroxyl groups. The ratio of peak density to valley value of teak waste nanofibrillatedcellulose is about 1.16∶1. The static bending strength (MOR), elastic modulus (MOE) and internal bonding strength (IB) of forest biomass materials were 115.27 MPa, 10797.43 MPa and 0.973 MPa, which are 5.1 times, 2.5 times and 4.5 times higher than that of teak waste fiber material, respectively. Meanwhile, the swelling value of thickness after water absorption was only 5.77%, which is 76.88% lower than the teak waste fiber material, demonstrating the dimensional stability. The profile density, MOR, MOE, IB and TS of forest biomass materials are superior to teak waste fiber material.
