Research and Development Bonding pretreatment of FRP using low-pressure blasting
  • 13 Downloads

Bonding as a laminar joining technology allows a high degree of utilization of the lightweight potential of fiber-reinforced plastics (FRP). But for this purpose, a suitable pretreatment of the surface is required. For serial production, low-pressure blasting is recommended which enables the bonding pretreatment of FRP with high reliability and low process times.

The use of fiber-reinforced plastics (FRP) in the automotive industry is no longer limited to the smallest-batch series of expensive sports cars, at least not since the announcement that the BMW i3 will have a Life-module made of carbon fiber-reinforced plastics (CFRP) [1]. But there are still considerable challenges as regards the bonding of these materials, as conventional procedures (for instance spot welding) cannot be applied and technologies using mechanical fasteners lead to a local destruction of the fibers and considerable stress peaks. The use of adhesive bonding is recommended which, however, requires a...

The presented results were developed within the AiF ZIM project FaVaBond and the research program “Bürgernahes Flugzeug” which has been sponsored by the state of Lower Saxony since 2009. The project FaVaBond was funded by the federal ministry for economy and technology on the basis of a decision of the German parliament. The authors would like to thank the partners of the participating research institutes of the DLR, TU Braunschweig and LU Hanover as well as the project partner GP Innovation GmbH, Lübbenau, for the good cooperation in the projects.
