The results of modelling regular structures made of plastics and studying their destruction can be effectively used as a starting method for development of a technology for manufacturing composite materials. Numerical experiments and field tests helped to determine the most preferred types of structures – plasstic-based honeycomb structures with the following strength properties: Young’s modulus, Е = 342.3 MPa, compressive strength, σ = 20.4 MPa, specific strength, σsp = 81 MPa cm3/g. Plastic 3D models were utilized in manufacturing of metal composites using a technology combining selective laser melting of titanium frame from powders and infiltration with more fusible alloys. The values of the transverse rapture strength change within the range from 1440 to 1560 MPa, the values of the Young’s modulus – from 49,500 to 54,000 MPa, hardness – 400HB. The increased strength values can be explained by the composite structure of the material formed by the combination of two mutually penetrating frameworks.
