| Abstract: | In this paper,the impact strength of PP and its composites are studied by adding some amount of aluminum powder and porous powder.The test results show that the heat resistance of the composite is the best when the content of metal aluminum powder is 2wt%and the content of porous powder is 7wt%.When the content of metal aluminum powder is 2wt%and the content of porous powder is 9wt%,the tensile strength,impact strength and spherical indentation hardness of the composite are 21.14MPa,1.62MPa and 61.0N/mm 2,respectively.At this time,the composite has good comprehensive properties. |
