Edgewise Compressive and Fatigue Properties of Brazed Titanium Sandwich Constructions.
Abstract
Sandwich constructions having titanium facings brazed to titanium honeycomb core with aluminum braze were evaluated in edgewise compression under static and fatigue loading. Static edgewise compressive properties parallel to the core ribbon direction were evaluated at temperatures up to 1200F. Edgewise compression fatigue and shear fatigue tests were made at 75F. The edgewise compressive strength at elevated temperatures, compared to strength at 75F, was about 60 percent at 800F and about 20 percent at 1200F. The maximum alternating stress at 30 million cycles in edgewise compression fatigue tests approached 90,000 pounds per square inch. The maximum alternating stress at 30 million cycles in flatwise shear fatigue tests approached 125 pounds per square inch. (Author)
