Abstract:

The performance of diffusion-bonded titanium sandwich constructions was determined by evaluating flatwise shear, flatwise tensile, and compressive properties at room temperature. Shear and flatwise tension fatigue data were also obtained at room temperature. Edgewise compression tests were conducted on sandwich with three different facing thicknesses at temperatures up to 1200F. Fatigue loading of edgewise compression specimens was done at room temperature. Shear fatigue strength approached about 10 percent of static shear strength and flatwise tensile fatigue strength about 5 percent of static strength. Edgewise compression fatigue endurance limit was from 60 to 70 percent of static strength values. Effects of increasing temperature dropped static edgewise compressive strength, especially at 1200F.
