Abstract
In order to recycle the waste peanut hull and TPU(thermoplastic urethanes), the composite made from peanut hull powder which was used as reinforcing material and TPU which was used as matrix material by the method of blending and hot pressing was discussed. The parameters of molding process were designed by orthogonal experiment. The tensile property, bending property and impact property of composite materials were tested in this study. The molding process parameters were optimized with the methods of range analysis and single factor analysis. The results showed that the optimum conditions were given as followings: concentration of peanut hull powder was 60%, hot pressing temperature was 170°C, hot pressing pressure was 12Mpa, and hot pressing time was 5min. Under above conditions, excellent mechanic properties were achieved, which were that tensile strength was 19.63MPa, bending strength was 25.74MPa, impact energy absorption was 1.33 KJ/m2.
