An analysis of modern technologies for manufacturing components and bearing systems made of composite materials has been conducted. These technologies are based on the polyester resin injection method and do not require high financial costs in manufacturing. The proposed method, due to the low cost of tooling, is convenient to produce a wide range of items made of composite materials, both in large-scale and single-piece production. Composite materials are intensively used in automotive industry, especially for motor racing vehicles’ parts. These technologies allow to solve the problem of creating ultra-light assemblies for modern car bodies, energy-absorbing passive safety elements and other high-loaded parts. They provide better strength and weight characteristics and better specific energy-output ratio of passive safety elements, as compared to conventional materials (metals and plastics). Considering the above, the most appropriate technology for the automotive industry has been assessed with that choice substantiation.
