  • Publication number: 20250185226
    Abstract: A composite material self-wrap shielding tube includes: a plurality of carbon fiber bundles disposed extending in a longitudinal direction; a plurality of wire bundles alternately disposed with the carbon fiber bundles and composed of metal wires; and a plurality of weft yarns disposed extending in a direction perpendicular to the carbon fiber bundles and the wire bundles. The composite material self-wrap shielding tube is formed by winding, into a cylindrical shape, a braided member made by braiding the carbon fiber bundles, the wire bundles, and the weft yarns.
