Abstract Theoretical analysis and experimental tests were conducted on the filament winding of a combined revolution body with a concave surface. The critical criterion of no fiber bridge is derived based on the force analysis of the fiber, and the design feasibility of the uniparted hyperboloid as a concave surface to avoid the fiber bridge is discussed. A combined revolution body mandrel with a concave surface was designed and fabricated. The integral winding feasibility of the combined revolution composite shell made of T700-12k carbon fiber/epoxy resin composite and rubber is analyzed, and the concave surface structure is verified to be free of a fiber bridge. The burst position is located in the cylindrical part and the concave surface structure is verified to be safe through a burst pressure test. The present investigation can provide theoretical guidance for the winding of a combined revolution body with a concave surface.
