Study on the properation and properties of PP/mental aluminium power composites

Abstract

In this paper, polypropylene(PP) was blended with aluminum powder, porous powder and EVOH reinforcing agent in different proportions by melt blending method. The infrared spectrum analysis of the blending components was carried out to study the tensile strength, impact strength, ball indentation hardness and heat resistance of the composites with different proportions. The results show that when the content of aluminum powder is 2 wt.%, the content of porous powder is 9 wt.%, and the content of EVOH is 4 wt.%, the heat resistance of the composite is the best. The tensile strength, impact strength and hardness of the composite are 21.33 MPa, 1.83 MPa and 74.78 N/mm 2, respectively. At this time, the composite has the best comprehensive properties.
