EnglishAn original method to increase the mechanical strength of adhesively joined carbon fiber-reinforced plastics (CFRPs) and honeycomb CFRP sandwich structures by etching is proposed, based on sulfuric acid etching of the CFRP surface. Etched composites are joined by a novel phenolic resin-based adhesive and are cured, and their cross section is observed by FESEM. Etching of CFRP was aimed to obtain a “brush”-like composite to be infiltrated by the adhesive, giving a fiber-reinforced, stronger composite joint. This method gave a 100% increase in the lap shear strength for the adhesively joined etched CFRP, compared to the non-etched ones.
