Abstract: Sandwich structure is well known for its great stiffness and strength while also cheaper and lighter than solid material. Among various types of core material, honeycomb core has the best stiffness-to-weight ratio and excellent fatigue resistance. Honeycomb cores can be made by different kinds of materials such as aluminum and aramid fiber composite (Nomex®). Along with the broadened range of composite sandwich structure application, superior honeycomb core material that has higher strength and stiffness-to-weight ratio than the traditional honeycomb material is necessary. Also, moisture absorption and corrosion damage of the traditional honeycomb material need to be solved. In this study, composite sandwich structure with the carbon fiber reinforced composite honeycomb core fabrication was demonstrated. The core was manufactured by bonding the corrugated carbon fiber strip that was laid and cured on the aluminum mold. The facesheet was bonded to the honeycomb core and cut to the compression test specimen size. The compression test was conducted using composite sandwich structure with carbon fiber composite, aluminum, and Nomex® honeycomb core.
