Honeycomb sandwich panels, which is a kind of composite panel structure, are composed of thin plate surfaces and honeycomb cores, and utilized in various industrial fields because of their properties such as lightweight and high rigidities. However, JIS standards for experimental evaluations on mechanical properties of such honeycomb sandwich panels bonded with different material-made thin surfaces and honeycomb cores are not standardized. Therefore, this research introduces adhesive-bonded composite panels composed of aramid honeycomb structures or aluminum honeycomb structures as panel cores and CFRP (carbon fiber reinforced plastic) laminate plates as panel surfaces for experimental approaches. Bending experiment results of such composite panels were utilized to grasp the influence of the design parameters like constituent materials and structural dimensions of composite panels on bending rigidity and specific bending elastic modulus etc. Furthermore, analytical evaluation on the honeycomb-cored composite panels were performed using finite element analysis software ANSYS. Comparisons between analytical and experimental results were executed to confirm the validity of analytical approaches on high performance evaluation of such composite panel structures.
