Abstract: Graphite-Cr 3 C 2 -carbon fibre composites were fabricated by spark plasma sintering at 2000 °C under vacuum and 30 MPa of pressure. Composites with 2.5, 5.0 and 10.0 vol % carbon fibres and 15 vol % Cr 3 C 2 were prepared to analyse the thermal, electrical, and mechanical properties. The single addition of 15 vol % of Cr 3 C 2 is sufficient to improve 27 times the electrical conductivity, 12.5 times the thermal conductivity and 4.7 times the flexural strength. The carbon fibres provide only an improvement in thermal conductivity, which is 1.67 times greater than that of the composite graphite-15 vol % Cr 3 C 2. The best composite is that consisting of graphite-15 vol % of Cr 3 C 2 -5.0 vol % carbon fibres, which has in the in-plane direction: 360 W m−1 K−1 of thermal conductivity, 1.09 MS m−1 of electrical conductivity and 106.46 MPa of flexural strength, which are 21, 27 and 4.45 times that of graphite, respectively. The anisotropy ratio of 120 was determined by synchrotron radiation X-ray diffractometry. [ABSTRACT FROM AUTHOR]
