Thermoplastic styrenic elastomers(TPS) are physical mixtures of polymers. They are used for automobile parts and sports products to suppress vibration because of its mechanical properties. In this study, CFRP / TPS sandwich composite materials with damping TPS sheet were developed, and the mechanical properties were investigated. At first, the biaxial tensile loading tests were conducted to investigate static mechanical properties of the TPS. The hyperelastic model was applied to representation of the experimental results. Next, the 3-point bending tests were conducted to investigate the bending characteristics of CFRP / TPS sandwich laminates. The test result showed that, the bending stiffness was decreased by the TPS in the CFRP specimens. In the FEM analysis based on the hyperelastic model, the bending characteristics of the CFRP / TPS laminated board in the low strain region could be reproduced.
