The paper presents the results of studies on production of layered composite materials, based on aluminium and titanium alloys, by vacuum diff usion welding, with a broad range of specifi c weight values, which is achieved due to diff erent layer ratio in each of the composites. Based on a layered composite material, a procedure was proposed for manufacture of three-layer honeycomb panels by vacuum diff usion welding. It is found that the average compressive strength of the three-layer panel with a fi ller from a layered composite material based on Al–Ti alloys is equal to 47.3 MPa, that is four times higher that the strength of similar honeycomb elements made from an aluminium alloy. It is shown that the layered material has higher thermal stability, compared to aluminium alloys. Sample annealing at the temperature of 700 °С for 30 min does not lead to their early destruction or loss of shape. 8 Ref., 3 Tabl., 7 Fig.
