In view that the metal rubber (MR) on the forming direction can bear larger load, but has the disadvantage of low tensile and shear resistance, and according to the characteristics of MR wire overlapping each other, the resistance structure model of MR was analysed and constructed. Current sintering method based on skin effect was put forward. Analysis and calculation of wire skin depth, equivalent resistance, joule heat was carried out on the basis of using 20MHz, 10A,10min alternating current sintering experiment, and resulted in the MR internal formed part of fusion welding where contacted. The tensile deformation and shear performance of MR after sintering are better than that of non-sintered MR. The results show that the mechanical properties of the MR can be improved based on the skin effect current sintering, and thus increase the service life and expand the application field.
