The characteristics of composite materials in the system Al₂O₃– carbon nanotubes – eutectic additives are investigated. The effect of the content of the reinforcing component as well as high-temperature heat treatment in vacuum on the strength of the material is examined. The obtained samples with 0.4 wt.% carbon tubes had the following characteristics: average tensile strength in three-point bending 380 MPa, open porosity 0.9%, average density 3.71 g/cm³.
