The present work aims to investigate the buckling performance of sandwich structure of functionally graded carbon nanotube-reinforced composite (FG‐CNTRC). Through first-order shear deformation theory, an analytical model for the sandwich structure of FG‐CNTRC was established. The governing equation for the prediction of the buckling performance of the sandwich structure of FG‐CNTRC was obtained through energy method. There was analytical solution that can satisfy both boundary conditions. The theoretical model and method were verified by literature analysis, and the influence of each parameter on the buckling performance was evaluated and performed on the basis of the corroborated model. The findings can lay a solid foundation of the design and application of the sandwich structure of FG‐CNTRC.

“…In addition to the inherited excellent performance of the FG-CNTRC, the FG-CNTRCDS also exhibits an improved damping performance due to the added viscoelastic damping films. Even though the dynamic performance of FG-CNTRCDS, which is simply supported by four edges, has been studied using the FSDT and the Hamilton method, [37] investigations on dynamic properties of such a structure under clamped boundary conditions have not been reported. Facing these problems, the authors developed a dynamic analytical model for clamped boundary conditions, which is based on the structure's geometric equations, the constitutive relationship, and the HSDT rather than the FSDT with the purpose of studying FG-CNTRCDS's dynamic performance.…”

Multi-phase functionally graded carbon nanotube-reinforced composite damping structure (FG-CNTRCDS) excels other composite structures in that it inherits the excellent performance of the functionally graded carbon nanotube-reinforced composite, and exhibits an improved damping performance due to the added viscoelastic damping films. Despite its superior properties, investigations on dynamic properties of the FG-CNTRCDS under clamped boundary conditions are still lacking. Aiming at filling this gap and paving the way to accurately design and analyze the FG-CNTRCDS, a dynamic analytical model, which is based on the higher-order shear deformation theory to formulate governing equations for predicting free vibration of FG-CNTRCDS, has been established. The analytical solution that satisfies clamped boundary conditions is obtained using the Rayleigh-Ritz method. The existing analytical results from the literature have been used to verify the correctness of the theoretical model. In addition, effects of various structural parameters (such as volume fraction and core-to-skin thickness ratio) on dynamic performance have been investigated. Here, the dynamic performance refers to the first-order natural frequency and the first-order loss factor.

The high temperature co‐curing damping composite was investigated by co‐curing technology to improve the mechanical property and damping performance of the traditional fiber reinforced resin matrix composite. Fluororubber with stable chemical properties and high‐temperature resistance was used as the core layer of novel carbon fiber reinforced bismaleimide resin matrix High‐temperature Co‐curing Damping Sandwich Composites (HCDSC). The curing temperature and curing time of fluororubber were consistent with that of bismaleimide resin by adjusting the formula. The viscoelastic damping properties and thermal stability of zinc methacrylate reinforced fluororubber were investigated in detail. Static mechanical tests, modal tests and interfacial shear tests prove that HCDSC display excellent mechanical and damping properties. The interfacial microscopic analysis reveals that viscoelastic sandwich materials are closely bonded with the composites. The dynamic characteristics of damping sandwich composite plate with fixed support on four sides is analyzed theoretically, and the vibration equilibrium equation of composite plate is derived by combining first‐order shear deformation theory, variational principle, and Hamilton principle. The damping performance of the composite plate are discussed through modal tests to verify the accuracy of theoretical derivation. This research is of great significance to solve the problem of structural dynamics, and provides a new idea for the design of structural and functional composite materials.Highlights A viscoelastic damping material with large damping and high strength was prepared. The dynamic performance of co‐curing sandwich composite structures was studied. The free vibration of composite structures was explored via experiment and theory.
