    摘要： A carbon fiber surface oiling agent changing apparatus includes a feeding module, a receiving module, a desizing module, a plasma surface treatment module, and a sizing module. A carbon fiber yarn released from the feeding module is sequentially processed at a predetermined speed to perform the steps of desizing, plasma surface treatment, sizing, and so on, in a relatively more active and reliable manner. Particularly, the surface of the carbon fiber yarn is roughened and is provided with functional groups, which is beneficial to achieve high-quality interface bonding of the carbon fiber yarn and the matrix resin in the subsequent sizing step, thereby enhancing the characteristics of carbon fiber composite materials.

    摘要： A graphene composite fiber includes graphene sheets and a polymer for aggregating the graphene sheets together. The polymer includes either or both of a hyperbranched polymer and polyvinyl alcohol. The graphene sheets and the polymer are stacked on each other to form a layered structure, and the graphene sheets are regularly arranged along an axial direction of the graphene composite fiber. In a production method of the graphene composite fiber, a graphene oxide is used as a raw material, which significantly improves tensile strength of the graphene composite fiber. Addition of the polymer provides good tenacity for the composite fiber. In a spinning process, rotated coagulant is used to increase a tensile force of a gelatinous fiber, so that the gelatinous fiber has high orientation and tacticity, thereby significantly improving strength of an obtained solid fiber. The final reduction process restores electrical conductivity of a graphene fairly well.
