Comparative tests are performed during repeated tension of structurally similar samples of fuselage panels with a SIAL-3-1R laminated aluminum–glass-reinforced plastic (GRP) shell and a shell made of aluminum alloy 1163 sheets, and their fatigue life until cracking and complete failure is determined. Instrumental methods of monitoring the integrity of the structure with the registration of cracks up to 5 mm long and monitoring their growth have been tested. Fractographic studies of the crack development of in the layered aluminum–GRP material are carried out. The advantages of using a metal–polymer layered material as the shell of aircraft fuselage panels in comparison with a traditional aluminum alloy are shown.
