Possibility for improving damage tolerance of integral structure by high strength bonded straps
Original language description
Integral stringer panels can attain weight reduction in a primary aircraft structures, but does not contain physical barriers for fatigue crack growth. One of the promising technique for prolonging fatigue life are bonded crack retarders made of materials with high stiffness. Experimental study was done on two specimens with different geometries. The straps consisted of high strength corrosion resistant steel AISI 301 was adhesively bonded to an aluminium alloy 2024-T351 Center-Cracked Tension (CCT) specimens fabricated by a high-speed machining process to promote fatigue crack growth retardation. Specimens were tested at constant amplitude load. The study concludes that the fatigue crack growth life can be significantly improved.
