Aramid organoplastics with increased resistance to climatic factors

Abstract

The article describes the stage-by-stage development of Russian aramid fibers. The differences between the third generation of Rusar NT fibers and CBM and Ruslan fibers are described. In this work, we studied the resistance of a structural organoplastic based on the third generation of Russian aramid fibers to various climatic factors in order to justify the possibility of using the material in all climatic conditions. For structural organoplastics reinforced with aramid fibers capable of absorbing moisture, the humidity of the environment is a particularly significant factor of influence. When developing all-climatic organoplastics, the key issue is to increase the resistance to moisture absorption and ensure the stability of mechanical characteristics during water and moisture absorption. For the first time for a Russian aramid organoplastic, it has been shown that due to high moisture resistance and a high level of preservation of physical and mechanical properties after exposure to a wide range of climatic tests, organoplastic grade VKO-25 can be considered for use in aviation products operating in all climatic conditions.
