Presents the results of experimental studies of the effect of additional apparet on the properties of high-temperature carbon plastic based on a heat-resistant thermosetting phthalonitrile binder and a volume-reinforced woven preform. Comparative data are given on physical and mechanical properties of carbon plastics based on preforms with and without an apparet, including after exposure to operational factors (thermal aging, water and moisture absorption), results of thermal analysis and microstructure research.

Provides an overview of scientific and technical literature in the field of application of polymer composite materials in the automotive industry. The paper presents the history of the issue, as well as current trends in the field of materials, technologies and the technical solutions used to solve the assigned tasks. Taking into account world experience. examples are given and the prospects of using polymer composite materials and technologies for their processing developed for the aerospace industry in automotive industry are shown.

The article studies influence of laboratory-simulated external influencing operational factors – water and moisture saturation, combined effect of elevated temperature and humidity, exposure in a tropical climate chamber on the properties of high-temperature carbon fiber based on a melted thermosetting polyimide binder. Studies of the structure, glass transition temperature and elastic-strength characteristics of carbon fiber after exposure were carried out, the change in the mass of carbon fiber samples during long-term exposure to water and moisture was estimated.
