Investigations on low-energy impact and post-impact fatigue of adhesively bonded single-lap joints using composites substrates

This paper presents an extensive investigation on the low-energy impact damage and post-impact fatigue of composite/steel and composite/composite adhesive joints experimentally and numerically. Using carbon-fiber and glass-fiber reinforced plastics (CFRP and GFRP) as well as high-strength steel (HSS), four kinds of adhesive joints were fabricated, i.e., CFRP/CFRP, CFRP/HSS, GFRP/GFRP and GFRP/HSS single-lap joints (SLJ). The impact damage of the...
