Metal-fluoroplastic materials for aviation structural elements

Abstract

The paper presents the analysis of metalfluoroplastic materials. Russian metal-fluoroplastic materials are not meeting the requirements of regulatory and technical documentation which was adopted by Russian aircraft industry. The review of patents in the area of the methods for obtaining metal-fluoroplastic materials (MFM) was given. Perspectives of development were revealed. These perspectives of development can significantly increase the operational characteristics of metal-fluoroplastic materials. Their use allows increasing the thickness of the work polymer layer tenfold in comparison with traditional materials, and increasing work service and reliability of dry friction components. It is established that the preliminary mechanical treatment of bearing surface of the metal-fluoroplastic material allows ensuring the production of products with high accuracy and working without lubrication for a long time.
