An integrative joining technology between steel and carbon fibre-reinforced
plastics (CFRP) is presented for lightweight design applications in aviation
Small spikes are welded onto metal surfaces via "cold-metal transfer" which
then build up a fibre-friendly fixation through form-closure with co-cured
Manufacture of such reinforced hybrid specimens and results of static tensile
testings are discussed.
Video-extensometry is applied to characterize the hybrid joints in terms of
strength and failure history.
Comparisons with epoxy bonded references show improvements in ultimate load,
maximum deformation and energy absorption capacity.
