Infrared Thermography During Bonding and Sealing
Precisely Testing the Quality of Joints Non-destructively
From the car body to the headphone – innovative material mixes made of modern fibre composites and well-tried metals are playing a more increasingly important role as materials in lightweight construction for industrial and household goods. The most varied composite fibre materials, such as carbon-fibre reinforced plastic (CFRP) and glass fibre reinforced plastic (GFRP), are combined with aluminium and magnesium as well as with high-strength and ultrahigh-strength steels. Joining such multi-material mixes imposes partially very high demands on the technology and manufacturers involved in this.
Bonding and sealing have established themselves as practicable joining technologies besides riveting, screwing and clinching. Thus, for example, the typical large contact surfaces facilitate the strength of large, thin lightweight composites for bonding. Consequently, components with less wall thickness and thus less weight can be installed. At the same time, the use of adhesives and adhesive tapes increases technological flexibility. Both can be processed manually and automatically. This opens up new possibilities for the production of single pieces as well as for serial production.
