Abstract
Mg-2 wt.% Li matrix composites unidirectionally reinforced with T300 and Granoc carbon fibres (∼ 45 vol.%) were prepared by the gas pressure infiltration technique. Lithium alloying stimulates the interfacial bond formation and at the same time causes the damage of carbon fibres by Li2C2 formation. Auger electron spectroscopy was used to detect Li2C2 inside the carbon fibres. The maximum flexural strength (1210 MPa) was achieved in Mg2Li/T300 composites at the shortest infiltration time (5 s) and then decreased monotonously with infiltration time prolongation (up to 60 s). Strengthening in Mg2Li/Granoc composites was much lower when maximum bending strength of 579 MPa was reached.
