Graphene nanosheet has been brought to the B 4 C/Al composites to investigate the microstructure and mechanical properties of the materials which were prepared via vacuum hot press sintering at 680 °C, with sintering pressure of 30 MPa and soaking time of 90 min. XRD analysis illustrated that there was only one new phase AlB 2 detected out in the composite after sintering. The composite without GN addition was endowed better density than the GN addition one. Nevertheless, the mechanical properties of GN addition composite exhibited more superior than that of non GN addition composite, Vickers hardness, bending strength and fracture toughness were achieved respectively 54.13 ± 4.57 Hv, 238.36±10.24 MPa and 4.23±0.12 MPam 1/2 . In summary, GN has played a satisfactory character in promoting the mechanical property of B 4 C/Al composites in the present experiment.
