ONSERT joining technology demonstrated on BMW i3

摘要

Assembly specialist Bollhoff and adhesives expert DELO have developed a bonded bolt technology called ONSERT which has been demonstrated in a pilot project on the BMW i3 electric vehicle. ONSERT can be used with composites such as carbon fiber reinforced plastic (CFRP), which is rinding increasing use in the automotive industry, as well as thin sheet metals, plastics and other materials. The joiningtech-nique combines the advantages of bonding technology with those of detachable screwed connections. Fastening elements, such as threaded metal bolts, are fitted a transparent plastic base, which is bonded to the composite material using a light-curing adhesive.
