ANALYSIS OF MODERN TECHNOLOGIES FOR THE MANUFACTURE OF CRYOGENIC STRUCTURES OF ROCKET AND SPACE TECHNOLOGY FROM POLYMER COMPOSITE MATERIALS

The modern state of technologies for manufacturing cryogenic structures of rocket and space technology from polymer composite materials is studied. The application of composites based on carbon fibers in the creation of fuel tank structures for cryogenic fuel components: liquid hydrogen (LH2) and liquid oxygen (LOX). An analysis of the world state of modern technologies for the manufacture of cryogenic structures of rocket and space technology from polymer composite materials has been carried out. Prospective and experimental examples of the worlds leading companies were considered, as well as the trend in the development of technologies and methods of their creation was determined. The requirements and technological parameters of the process of forming large-sized products by automated production methods from polymer composite materials are defined. Prospective areas of development have been identified, such as automated tape laying (ATL - Automated Tape Laying) and fibers (AFP – Automated Fiber Placement), which allow the implementation of modern technologies and materials in rocket engineering, which allows adapting composites, including for work in a cryogenic environment . The promising technologies considered are sufficiently productive and meet the requirements for mass production. The implementation of new methods of automated laying of tape and fibers made it possible to research and implement new combinations of materials, and to use a wide range of them in solving the tasks. The wide distribution of classic technologies for obtaining products from polymer composite materials by the method of wet and dry winding is noted.
