High-performance film adhesives are often employed in aerospace composite structures to provide adequate adhesion between substrates. This study was performed to evaluate the fracture properties of a commercial film adhesive and a carbon fiber prepreg material in both co-cured and bonded applications. In addition, the fundamental reasons for macroscopic fracture properties were evaluated on the microscale using interphase analysis and surface analysis techniques. From this information, it was possible to examine the commingling of prepreg and adhesive resins in the bond line interphase region. The information presented in this study points to a critical aspect of material selection and utilization that is often not considered in composite design: resin compatibility. *Dedicated to Prof. Francisco J. Balta Calleja on the occasion of his 65th birthday.
