In order to conduct surface modification more effectively, we have investigated the in-mold surface modification technique for composite surface that uses microstructures fabricated by imprint lithography. In the present study, we performed end notched flexure (ENF) tests to evaluate the resistance to crack propagation under macroscopic mode II loading at the modified carbon fiber reinforced plastic (CFRP)/adhesive interfaces by comparing the behaviors of brittle adhesives and ductile adhesives. In addition, we also investigated the influence of the aspect ratios (A) of the microstructures on the fracture toughness. From the ENF tests and microscopic observation of crack propagation, the mode II interfacial fracture toughness (GIIC) of the modified surfaces were found to be improved than that of flat surfaces regardless of applied adhesives. In the case of applying Epoxy A (3M DP-100 clear), which has a Young×
