Effect of Al Powder on Mechanical Properties of Sintered Parts with Nylon 12 Composite Powder
The effects of Al powder contents on the mechanical properties of composite nylon powder were investigated.The results show that in certain range,with the increase of aluminum content,the mechanical properties of the samples improve;the tensile strength,flexural strength of the sintering specimen improve with the aluminum content increasing,the tensile strength and bending strength of the composite powder reach the maximum 40.1 MPa,45.6 MPa,respectively,extension rate of 7.28% when the aluminum powder content is 40%.After aluminum powder content exceeds 40%,the mechanical properties of the sintered samples decrease,the best amount of the aluminum powder is 40%.
