This is my summary of research findings sent to me by material engineer Max Wagner, for global automotive fastener supplier Nedschroef (Helmond, The Netherlands), based on a large development program conducted at its Techno Centre, also in Helmond.
Why research fasteners for CFRP
Because only serious weight reductions will result in extended driving range for electric vehicles, the future of e-mobility depends on progress in lightweight solutions. Though carbon fiber reinforced plastic (CFRP) plays a major role in the next generation of these lightweight solutions, until recently, it was only used in exclusive, high-end models. BMW is the first OEM to use CFRP for larger volume production, with both i3 and i8 models using CFRP for most internal structure and body components to compensate for the added weight of electric engine, battery and control systems.(…)
