A review study in ultrasonic-welding of similar and dissimilar thermoplastic polymers and its composites

Abstract

Due to the use of integrated materials in aerospace, automotive, sportswear, wind turbine and other fields, the industry is demanding new technologies and is rapidly adapting to more complex composite structures. In the last several years, unlike traditional welding methods, ultrasonic joining has become an important relevance in many applications areas. The random distribution and poor mechanical characteristics of grain always make it difficult to connect dissimilar materialsin the conventional welding process. The Ultrasonic-Welding technology for joining thermoplastic (TP) compounds is fast and energy efficient. Compared to other joining processes (adhesive, mechanical etc.), this welding method is more economical. This review's key features are the Ultrasonic-Welding process, theory, advantages, and limitations, process parameter, the effect of Energy director (EDs), Ultrasonic-Welding (UW) of similar and dissimilar TP composites and TP. The present state of UW and future viewpoints of TP composites are also explored.
