Fatigue and residual strength investigation of ARALL(R) -3 and GLARE(R) -2 panels with bonded stringers

摘要

Stiffened panels were fabricated from ARALL-3 and GLARE-3 laminates for the purpose of providing improved structural performance of lower wing panels for aircraft. To verify the designs fatigue crack growth and residual strength tests were conducted and compared to those for conventional monolithic aluminum panels.
