Fusion Bonding of Thermoplastic Composites with Dissimilar Materials

摘要

In recent years, it has become increasingly evident that designers no longer will persist in making a structure with the historically acceptable materials. Rather, materials offering the best combination of properties will be associated in a process involving joining. When producing joints between polymeric materials and metals, many technical difficulties arise. Dissimilarities in mechanical, thermal and chemical behaviour are just some of these. Current technology for joining dissimilar materials is in its infancy. Traditional technologies such as mechanical fastening and adhesive bonding are either too intrusive (stress concentrations resulting from hole drilling in mechanical fastening) or require extensive surface preparation incompatible with mass production requirements. The objective of this study is to investigate the application of resistance welding to the joining of thermoplastic composites with dissimilar substrates such as metals and thermosetting composites.
