The invention relates to a plain weave three-dimensional multilayer cylindrical or cylindrical special-shaped braided fabric, which is a three-dimensional continuous cylindrical braided fabric formed by interlacing over three layers of warps and over two layers of wefts, wherein over two other layers of warps are inserted into every layer of warps; every layer of warps and other layers of warps are inserted in sequence layer after layer, and are encircled into a continuous cylinder; and every layer of wefts is orthogonally buckled in every layer of warps and is encircled into a continuous cylinder. In the three-dimensional multilayer braided fabric, every yarn fiber of every layer is tightly interlaced into a whole. The braided fabric has uniform stress, is a continuous cylinder with no seam, and has a tight structure; and the intensity and compression resistance of a cylindrical or cylindrical special-shaped composite material are enhanced effectively.
