Effect of Infiltration Copper or Aluminium on Flexural Strength of C/C Composite Materials

The flexural strength of C/C composite materials which infiltrated by copper or aluminium was investigated through the three-point bending method.The results indicate that the flexural strength of C/C+Cu and C/C+Al is 88,196 MPa respectively,which is higher than the C/C composite that is 77 MPa.Because of the interface joined intensity of C/C+Al is better than C/C+Cu,the flexural strength of C/C+Al is much higher than the C/C+Cu.Flexural strength of the C/C+Cu and C/C+Al have been up to even exceed the standard TB/T 1842.1-2002 for the slides made via powder metallurgy for electric locomotives.
