Joining of Plastics and Composites

The use of polymeric materials is nowadays increasingly in a many important applications including packaging, building, appliance, electronics, automotive, aerospace and much more. Polymers already have a range of applications that far exceeds that of any other class of material available. Joining is a critical step in the manufacture of components from polymers and polymeric composites. As the requirements for the component increase, so do the requirements for joining, especially in structural applications. The methods for joining plastics and composites can be divided into three major categories: mechanical fastening, adhesive and solvent bonding, and welding. Welding is an effective method of permanently joining plastic components. There are various welding methods. By reviewing and comparing all commercially available welding processes, this text helps the reader select the best-suited process for the application and provides an understanding on the limitations and benefits of each process. The focus on practical aspects such as weldability, and testing makes this text an indispensable tool for everyone involved in welding of plastics. At the same time, it also conveys the basic theoretical principles of plastics welding such as squeeze flow, molecular diffusion, and heat transfer mechanisms. Each section of this chapter was developed with information dealing with basic welding aspects including materials, process phenomenology, equipment, and joint design. While not all encompassing, the text provides the basic information along with references that can be used to gather additional information or details.
