Selection Of

Today wings for Boeing 787 and Airbus A350 aircraft are made of polymer composite materials in the form of prepregs based on carbon fiber, the blanks of which are molded in an autoclave. It is expected that by 2025–2030 will actively use the vacuum infusion method, which will require global research on the selection of binding and reinforcing materials, development of the vacuum impregnation and curing process, automation and development of new technological methods for laying out workpieces of parts, accelerating the process and shortening the cycle time.

The Matrix

The article considers the problem of the effect of uneven curing caused by the temperature gradient across the thickness of the material on the anisotropy of the strength properties of polymer composite materials. The effect of catalysts on the curing of the epoxy binder EDT-69N, used for the manufacture of multilayer polymer composite materials, was studied. According to dielectric spectrometry, the accelerating effect of the selected compounds on the curing process of the EDT-69N epoxy binder during fiberglass molding has been proved. The possibility of controlling the curing process using catalysts to reduce the influence of the temperature gradient on the anisotropy of the strength properties of the matrix in the manufacture of polymer composite materials is shown.

Selection Of

The object of research is the repair processes of parts made of polymer composite materials using a local heating element. The goal is the development of technology, the selection of equipment for repair of parts and assemblies from polymer composite materials using a local heating element and a vacuum source outside the production area, as part of the aircraft. In the process of performing the work, an analysis and review of the existing equipment for local repair of parts from polymer composite materials was carried out. Equipment for local repair of own and imported production was tested. Based on the results of testing and market analysis, equipment was selected that meets the requirements of ND for the manufacture of parts from polymer composite materials. A technical process for repairing parts using a local heating element and a device for hot gluing has been developed.

Railway Rolling Stock

The subject of improving the competitiveness and efficiency of railway rolling stock is highly demanded as the railway transport consider the nerve of the goods transport in the hole word. One of the requirements to develop the railway transport related to the continuous improvement of existing materials and find a new material which would satisfy such conflicting requirements as relia-bility, sustainability, producibility and the manufacturing process automation possibility. The researches show that use of polymer composite materials (PCM) in the production of both passenger and freight railway rolling stock, provides lightweight, improves its performance, increases durability and reduces operating costs.
