Outline of Final Research Achievements

Current industrial sectors, especially those in transportation industries, have been required to design lightweight structures for reducing CO2 emissions and fuel consumption through the economic and environmental policies. Due to these demands, metallic machine structural components are being increasingly replaced with lightweight polymeric materials. The aim of this work is the development of Novel Direct Joining Technique for Polymer-Metal by Using Ultrasonic Welding. Several surface modification methods were evaluated with the object of joint strength, morphology, and interface structure. As a result, higher joint strength is promised by nano-scale porous structure on the modified metal surface.
