Computer system for the formation of polymer composite materials for recycling

The article is devoted to solving the problem of forming polymer composite materials for recycling and predicting their properties using a web application developed in the JavaScript programming language (node.js). The architecture of the web application allows it to be used remotely at any point in production and from any modern device. The core of the web application is information support, implemented using the MySQL and Neo4j DBMS, including a database of characteristics of polymer materials, a knowledge base about the characteristics of polymer materials based on a product-frame model, a knowledge base about the compatibility of polymer materials, which is a semantic network containing information about polymers of various types, which ensures the flexibility of the software product. The result of the functioning of the system is the composition of the formed polymer composite material, namely, information about its composition, the values of the predicted properties (strength, density, elasticity) and the recommended method of recycling, determined by the melt flow rate of the composition. The use of a web application will reduce the amount of raw materials required for experiments to determine the optimal composition of the mixture, and will speed up the process of determining compatibility by a chemist-technologist, which will affect the increase in the volume of use of polymer waste in the production of new products.
