A nanomaterial-biomass fiber composite and preparation method thereof. The biomass fibers are cut or sliced, and then dried. The dried biomass fibers are mixed with a nanomaterial and conveyed to the preheating cylinder of a defibrator for cooking treatment. The cooked mixture is pushed between the grinding discs of the defibrator for hot grinding treatment. The resulting material is then hot pressed to obtain the nanomaterial-biomass fiber composite material. The preparation method benefits from simple operation, low cost, low energy consumption, suitability for industrialized production, and wide application prospect in the field of production of binderless fiberboard.
