Abstract
The automotive industries expect to replace conventional steel with CFRP to decrease fuel consumption. Adhesively-bonded joints are applied to many CFRP structures, and surface preparation is needed to indicate strong adhesion. However, conventional surface preparations increase process of works. In the present study, we propose in-mold surface preparation, and control the adhesion of the interface. In the in-mold surface preparation, the mold with the micro structures is transferred to the CFRP surface by pressure forming process. We evaluated the adhesion of CFRP/adhesive interface with in-mold preparation under mode II loading, and confirmed the validity of the in-mold preparation.
