Abstract
1.1 Background And Motivation Aerospace and automobile industries require lightweight, high-strength materials to decrease fuel consumption and an increase in payload. Commercially pure titanium and titanium alloys are widely used for aircraft as a material having light weight (density being 60% that of steel), high strength, and excellent corrosion resistance (Inagaki et al., 2014). Recently, the application ratio of CFRP (Carbon Fiber Reinforced Plastic) to airframes and engine parts has been growing to improve aircraft fuel consumption. Similarly, demand for titanium is also growing as it has excellent compatibility with CFRP with respect to corrosiveness and coefficient of thermal expansion issues (Inagaki et al., 2014). The amount of titanium used in the low fuel consumption aircraft A350XWB manufactured by Airbus S.A.S.; where a large amount of CFRP is used and has grown to more than twice the amount used in conventional aircraft (Inagaki et al., 2014). ..
