▎ 摘  要

The damping properties of carbon fiber reinforced polymer (CFRP) composites play a critical role in many engineering fields. The purpose of this paper is to investigate how the damping properties of CFRP composites can be improved by interfacial sliding of two-dimensional multilayer graphene oxide (GO). In this work, we show how the energy dissipation ability along the carbon fiber direction is enhanced by oriented GO at carbon fiber/ epoxy interface. The damping loss factor of CFRPs is measured by a dynamic mechanical analyzer. The effects of the GO on the damping properties of CFRPs are investigated under different sweep modes (temperature, frequency, and strain). The results show that the deposition of the GO on the surface of the carbon fiber can enhance the damping properties of CFRPs in a wide range of temperature, frequency, and strain domains. Quite significantly, the damping loss factor of CFRPs (0.0345) increases by 113% at a strain of 0.23% and a frequency of 1 Hz. Furthermore, a numerical parametric analysis based on the strain energy method is proposed in ANSYS to obtain the interphase properties of multilayer GO by reference to experimental data. The GO interphase damping parameters can be used to predict the damping properties of multilayer carbon nanomaterials modified composites under different service conditions.
