A high-toughness anti-split carbon fiber composite wire mandrel and preparation method thereof

Abstract

The invention discloses a high-toughness splitting-resistant carbon fiber composite wire core rod and a preparation method. The wire core rod is made of a plurality of kinds of fiber hybrid composite materials, wherein carbon fibers are adopted as main body reinforcing fibers. The wire core rod is composed of a rigid core, a flexible layer, an anti-splitting layer and a surface wear-resistant layer which are distributed from inside to outside sequentially; the rigid core is made of a high-performance carbon fiber composite material, so that the deformation resistance of the overall core rod can be ensured; the flexible layer is made of a glass fiber composite material, so that the toughness of the core rod can achieve winding of a certain curvature; the anti-splitting layer is made of a hybrid fiber helical winding structure, so that the splitting problem of the wire core rod in a winding process can be solved; and the surface wear-resistant layer is made of a carbon fiber surface felt or a two-dimensional braided high-performance fiber mixture, so that the surface wear-resistant characteristic of the wire core rod can be ensured, and the stability of the internal structural of the wire core rod can be effectively protected. With the multi-layer structured carbon fiber composite wire core rod of the invention adopted, the comprehensive mechanical properties of a current wire steel core or a traditional composite material wire core rod can be improved, and the service life of the current wire steel core or the traditional composite material wire core rod can be effectively prolonged.
