Preparation of Cf/Cu-C contact strip and wear behaviour under electric current
A novel carbon and copper fibre knitted fabric (C f /Cu) reinforced contact strip (C f /Cu-C) was fabricated by pyrolytic carbon deposition and resin impregnation-carbonisation process. The interface characteristics of the composite were characterised by a scanning electron microscope and a metallog...

/Cu-C) was fabricated by pyrolytic carbon deposition and resin impregnation-carbonisation process. The interface characteristics of the composite were characterised by a scanning electron microscope and a metallographic microscope; resistivity, mechanical strength and wear properties with electric current were also investigated. The results indicated that the C

combined quite well between phase contacting areas for each interface. With resistivity of 10.16 μΩ m and bending strength of 123 MPa, the as prepared composite outperformed the present AR129 carbon contact strip (density, 1.70 g cm
− 3
, resistivity, 33 μΩ m; bending strength, 40 MPa). The wear mechanisms of C
f
/Cu-C with electric current were proved to be slightly arc erosion and abrasive wear. |
