Основные проблемы внедрения методов переработки полимерных композиционных материалов и обеспечения технологических процессов при производстве морской техники

Abstract

In the past few years there could be seen an increasing use of polymer composite materials in the marine industry. Polymer composite materials reach 70% in the volume of parts and structures of ships and marine equipment. The most intensive growth in the implementation of composite materials can be observed abroad. The problem of complete or partial absence of domestic original reinforcing fibers and polymer matrices is revealed. The necessity to define the limiting factors for using the polymer composite materials in the shipbuilding industry of the Russian Federation is substantiated. A study of domestic and foreign literature, industry regulations was carried out, in which the deductive methods, analysis and synthesis were used. The ecosystem of organizing the technological process from the polymer composite materials in the production of structures and parts of marine equipment is considered. The specific features of the technological process are listed, and a formula that describes the speed of the infusion process and determines the parameters on which the process depends is given. It has been found that the main documents regulating the use of polymer composite materials in shipbuilding are focused on the production processes in the 1970s. Nowadays, a competitive struggle for the orders and deadlines forces to use computer-aided design systems for creating 3D models of parts and structures in designing complex structures. There have been defined the restraining factors that have a negative impact on the development of technological processes of working up and introducing the polymer composite materials in in the national industry. The results of the study will further serve to form methodological materials and options for designing technological processes for the processing of polymer composite materials in the Russian industry.
