Abstract
Chemical welding as an attractive alternative to classical joining techniques occurs through the formation of new chemical bonds between neighboring molecules at the contacting surfaces to be joined. This review paper presents the current state of the chemical welding of polyurethanes and their composites via dynamic covalent bonds. The strength of welded joints obtained by different welding technologies was compared. Different processing parameters affecting the joint quality, namely welding time and welding temperature were summarized. The future perspectives of chemical welding of polyurethanes and their composites were discussed in the paper.
Keywords: polyurethanes, composites, chemical welding
