21/10/2010, · The Vickers Hardness has a value of 46.9 MPa which is much higher than that of graphite at 16.8 MPa, but lower than the minimum value for ,carbon steel, calculated to be approximately 539.4 MPa. It is surprising that the conductivity is slightly more than that of graphite given the increase in sp 3 character, but this may be a result of the bulk properties of the composite rather than the ...
