In addition, using composite materials for the manufacture of a device for transporting semi-trailers on railway platforms was studied. The range of currently used composite materials is quite wide: fiberglass, polycarbonate, and thermoplastics. Based on the appearance of the reinforcing filler, composites are divided into: - fibrous (reinforcing component of the fibrous structure); - layered; - filled plastics (reinforcing component-particles); - bulk (homogeneous); - skeletal (initial structures filled with binder). Also, composites are sometimes classified by matrix material:

- with a polymer matrix; - with a ceramic matrix; - with a metal matrix; - oxide-oxide composites. The main advantages of composite materials are: - resistance to decay, corrosion, heating;

- the possibility of obtaining a detail of complex geometry in one technological operation; - the possibility of obtaining a product compatible with chemical and food products; - preservation of mechanical indicators during the entire service life under the influence of high and low temperatures; - no need to use expensive coatings; - ease of repair. The listed advantages became the basis for searching for options for non-metallic materials in constructing freight
