Abstract: The hemp stalk based fiberboard panels were manufacturing and the influence of different concrete additive amount and the different parts of industrial hemp stalk on the properties of industrial hemp stalk based fiberboard panels was studied. The results showed that, as increasing of concrete additive amount, the mechanical properties including IB、MOR、MOE of industrial hemp stalk based fiberboard were decreased, while the TS of industrial hemp fiberboard were greatly improved. Moreover, the properties of hemp stalk core based fiberboard panels were better than those of the hemp bast fiber based fiberboard panels.
