“…Structural porosity is one of the main qualitative characteristics of multilayer devices of adhesive assembly with variable cross section [17,18]. Porosity determines presence of the air inclusions in multilayer structure of material, therefore, directly affects its strength and other operational properties [19,20]. Ensuring the least pore volume fraction is important characteristic of possibilities of the technological method during production of multilayer devices [21,22].…”

Numerous studies in application of modern composite materials show that their advantages can be successfully implemented in manufacturing «smart» products. This study proposes an improved technological method of manufacturing multilayer environmentally friendly products with a variable cross section, which allows us to expand the possibilities of using modern polymer composite materials (PCM). The technology allows manufacturing products of the most complex geometric shapes, such as wind turbine blades. The aim of the study is the technological support of engineering production in the manufacture of multilayer products of variable cross section made from PCM. Scientific novelty consists in identifying the patterns of implementation and management of the manufacturing process of multilayer products of variable cross-section, and establishing the influence of structural and technological parameters of the manufacturing process on their operational characteristics. The relationship between the pressure of a hot directed air stream and the volume fraction of pores in the hardened material of a multilayer composite product with a variable cross section during layer-by-layer application is investigated. During the study, fundamental and applied principles of mechanical engineering technology, material resistance, adhesion theory, mathematical statistics tools and software were used to process the results of the experiment. Based on the results of laboratory studies, a methodology has been developed for effective prediction of pore content in the manufacturing of composite products. The introduction of the presented technology and the corresponding original methodology into production will reduce the complexity and energy costs of manufacturing composite products, improve their quality and reduce the impact of toxic components from composite materials on workers.

“…This pace of development has been facilitated by the use of additive technologies in various industries, such as engineering, medicine, aircraft and automotive industry, production of essential commodities, as well as the use of 3D printers for private use. As a rule, thermoplastic polymers are used as the main materials in 3Dprinting technologies [2][3][4][5], however, papers where thermosetting material is the basis of polymer matrix have been published recently [6][7][8][9][10][11].…”

The influence of 3D-printing technological conditions on the performance properties of master models has been investigated. It is shown that strength properties of master models depend significantly on two parameters: layer thickness and percentage of filling. Recommendations onthe choice of 3D-printing conditions for manufacturing master models, as well as products based on master models, are presented.

New halogen-containing oligoethers based on 1,1-hydroxy-2,2-di (4-hydroxyphenyl) ethylene and 1,1-dichloro-2,2-di (4-hydroxyphenyl) ethylene of various degrees of condensation were synthesized by the method of high-temperature polycondensation. Features are investigated and optimal conditions of synthesis of new oligoethers are defined. On the basis of polysulfone compositions with various maintenance of oligoethers are prepared. With usage of the modern methods of researches, it is shown that new composites surpass industrial polysulfone in the main physical and chemical and production characteristics.
