| Abstract: | Box-Benhnken experiment was carried out by using mechanical milling time,mechanical milling temperature and molding time.The preparation parameters of polylactic acid (PLA)/cassava residues composites were optimized by response surface method.The relationship between the response and experimental factors was obtained.The mathematical model and the interactive effect of each factor on the response value were used to determine the optimum tensile strength and flexural strength of PLA/cassava residues composites.The technological conditions were as follows:molding time is 5.99 min,mechanical milling temperature is 59.01 ℃ and the mechanical milling time is 33.42 min.The tensile strength of the composites is 44.125 6 MPa and the flexural strength is 66.83 MPa. |
