Abstract: The dosages of coupling agent, lubricant and antioxidant were selected as three factors for Doptimal design. The preparation process parameters for bambooplastic composite were optimized with response surface method. The mathematical relationship models of each response value with different variables were established, and the interactive effect among each single factor and the response value was studied. The optimized conditions for preparation of the bambooplastic composite were determined as with 5.82% of MAPP, 0 of antioxidant , and 050% of the lubricant. The properties of the composite prepared under the optimized technological conditions were with 13.34MPa of tensile strength, 18.74MPa of the flexural strength, 746.39MPa of flexural modulus, 6.57kJ/m2 of impact toughness, whose Vicat softening temperature was 101.95℃, and the melting flow rate was 089g/10min.
