Abstract: The article outlines one of the pressing problems - the need to develop new structural materials such as composite ones. The purpose of this paper is to develop in an accessible and compact form the basic concept, properties of composite materials, the spheres of applications of structures made of composites. At present, the prospects for the progress of structural materials are mainly associated with the development and widespread use of composite materials. The aim to improve the existing designs, to create new materials opens up the opportunities for the implementation of new design solutions and technologies. Heterophase systems are the systems representing composite materials obtained from two or more components while maintaining the individuality of each component. Composite structural materials are characterized by the following features: predefined compositions and components of the material; in the composition of the material, the components are present in a certain amount which provide the specified properties; on an inhomogeneous microscale and a homogeneous macroscale, the materials are homogeneous. Basically, the components of composite materials differ in geometrical feature. Components with continuity over the entire volume of the composite is called a matrix. The reinforcing component separated in the volume of the composition has a discontinuous feature. Matrix materials can be metals and their alloys, organic and inorganic polymers. With continuous features, the reinforcing components are the finely dispersed powder particles or fibrous materials found in nature. [5] Two types of structural materials are considered in the article: composite materials on a metal basis and composites on a non-metal basis. Technical-technological, physical, technological, mechanical and chemical characteristics and properties of composites are given. Based on the analysis, the properties of unidirectional composite materials on a metal and non-metal basis are revealed. As a result of the experiments, the fields of application of composite materials on a metal and non-metal basis were determined.
Key words: component, macroscale, microscale, matrix, reinforcing filler, zero-dimensional, isotropy, adhesion, whiskerization, carbon fiber.
