Study on Damping Characteristics of Graphite Oxide Reinforced Carbon Fiber Composites.

For carbon fiber reinforced polymer (CFRP) composites, the effects of interfacial sliding of two-dimensional multilayer graphite oxide (GO) on the damping characteristics of CFRP composites were studied. The damping loss factor of CFRP was measured by dynamic mechanics analyzer, and the effect of GO on the damping performance of CFRP was studied under different scanning modes (temperature, frequency and strain). The results show that the deposition of GO on the surface of carbon fibers can enhance the damping characteristics of CFRP over a wide range of temperature, frequency, and strain domains. A finite element parametric analysis based on strain energy method is proposed in ANSYS, and the interface characteristics of multi-layer GO are obtained by combining with experimental data. The damping parameters of GO interface can be used to predict the damping characteristics of multilayer carbon nano materials modified composites under different service conditions.
