Abstract

Despite the increased interest of designers to composite polymeric materials (PCM), aluminum alloys are the main structural material of the aviation industry. Particular attention is paid to aluminum-lithium alloys and hybrid materials based on them, such as SIAL, which are layered materials of a new generation. SIALs are layered hybrid metal-polymer materials, which consist of thin sheets of structural aluminum alloys and GRP based on adhesive melt-type binders and glass fiber fillers with different reinforcement structures. The article provides information on the preparation of the surface of the aluminum-lithium alloy V-1469, which was selected for use in SIAL for the manufacture of wing panel panels. In this paper, the issue of protecting such alloys from corrosion and giving their surfaces special properties, in particu-lar, ensuring good adhesion of epoxy adhesive binders, is considered. Various types of anodic oxidation of the surface of aluminum alloys for bonding are conside
