Comparative analysis of mechanical properties of laminates composed of layers of titanium alloy and titanium alloy metal matrix composite

Abstract

AbstractA method is described for obtaining mechanical property profiles for titanium alloy larninates and for titanium alloy and titanium metal matrix composite (MMC) layers composing the laminate. The properties used were bend stiffness, and bend strength and impact strength in the notched and unnotched states. A given mechanical property was normalised with respect to the titanium alloy and a property ranking ratio R1 obtained which compared the same mechanical property in all the materials with that property in the basis titanium alloy. Summation of the R1 ratios gave a material ranking ratio R3 which provided an overall property profile for each material relative to the overall property profile for the titanium alloy and allowed a ranking of the materials. The ratio method allows rapid and effective comparisons to be made of the mechanical properties of laminates and of their component layer materials and provides a quantitative measure of the advantages and disadvantages of a laminated microstructur...
