Adhesive bonding

Structural adhesive bonding for carbon fiber reinforced plastic components

For various applications, the connection of thermosetting CFRP components as well as the connection of metallic force transmission elements via a conventional adhesive bonding process constitutes the better alternative. Thus, also the material bond created by epoxy resin contributes to the high connection strength of the T-Igel® connection.

TEUFELBERGER has gained extensive experience with structural adhesive bonds for various structural CFRP components with metallic inserts.   

Due to their high lightweighting potential, adhesive bonds enjoy a long-standing tradition in connecting CFRP components to metallic components. As a result, enormous quantities of adhesive ride or fly along in sports cars and aircraft.

The quality of adhesive bonds depends on a number of parameters. They include:

  • the surface quality of materials to be joined
  • the adhesive bonding process
  • the chemical composition of the adhesive (depending on the material and the type of loading, either 2-component epoxy, acrylates, polyrurethanes, or elastic adhesives)
  • the ambient conditions
  • a bonding-compatible structure
  • an extensive quality inspection

At TEUFELBERGER, for various CFRP component projects also structural adhesive bonding is used, in addition to the patented T-Igel® technology. In many cases, it is combined with other joining methods such as geometrical form fits and bolted or riveted connections. Primarily, we rely on 2-component epoxy adhesive systems and have many years of series-production experience in the quality control of adhesive bonds (e.g., with the hybrid CFRP/aluminum rear axle stabilizer of the Porsche 918 Spyder) 

Our team of specialists will be happy to support you in designing your ideal joining technology for your fiber reinforced plastics and lightweighted metallic  components.
