Main directions of improving the development of technology for manufacturing products from polymer composite materials by the method of winding

Abstract

Abstract. The development of scientific and technological progress in mechanical engineering, energy, aerospace and other industries is unthinkable without the creation of new structural materials that can improve the most important parameters of engines, machines and mechanisms, assemblies, devices and increase their mass performance, reliability, service life of products and reduce their material consumption. Products and aggregates from polymer composite materials (PCM) can be obtained in various ways. In industrial production, the most widely used method of winding and pressing. Pressing can be carried out using a mixture of preliminarily fiber and a polymer binder. One of the most promising methods of forming products and assemblies from a variety of plastic is the method of winding with fiber, due to the fact that it creates the required filler structure in the factories depending on their shape and operation characteristics. All areas of effective use of polymer composite materials are reflected. This article discusses the technological capabilities and applications of traditional and new varieties of the method. Even, the results of an analysis of the prospects for the development of manufacturing technologies for products and aggregates from polymer composite materials using the winding method are presented. There are methods of dry and wet winding. Consider these winding methods. Winding is carried out on a mandrel mounted on a machine with numerical control. This method is also called the spiral winding method. Existing approaches to the development of mathematical models are described and created for the manufacture of complex structural elements, including products and an assembly with a curved spatial axis, and so on.
