Preparation and Related Properties of Carbon/Basalt Hybrid Fiber Composites Mixed with KH550 Modified Graphene Oxide

The design, preparation, and application of high-tech wind turbine blades are crucial for enhancing the performance of wind turbines. With the development of the wind power industry, researching high-quality composite materials suitable for turbine blades has become an urgent issue. Therefore, exploring high-performance composite materials is essential. This study conducted a comparative analysis of the performance changes in carbon fiber/basalt fiber hybrid composite materials with different contents of KH550-modified graphene oxide (SGO) and further examined the mechanism of SGO in the resin matrix. The results indicated that the incorporation of SGO significantly improved the properties of the fiber composites. Specifically, the carbon fiber/basalt fiber hybrid composite material with $1 \%$ SGO not only ensured good electrical conductivity but also maintained favorable mechanical and thermal conductivity properties. Compared to composites without SGO, the tensile and bending strengths increased by $\mathbf{6 4. 0 4 \%}$ and $44.60 \%$, respectively, while the thermal conductivity improved by $\mathbf{1 5. 3 8 \%}$, and electrical conductivity increased by $\mathbf{7. 9 0 \%}$. In summary, by incorporating SGO fillers, the performance of carbon fiber/basalt fiber hybrid composites can be effectively optimized, and the composite material with 1% SGO provides important insights for the development of high-tech wind turbine blade materials.
