A tubular structure comprising reinforcing fibers impregnated with a thermosetting polymer and a sheet of matrix material filled with an additive suitable for improving tribological and heat conductivity characteristics of the tubular structure. The reinforcing fibers alternate with the matrix material. The tubular structure is formed by winding the reinforcing fiber fabric and the matrix sheet material, wherein the fabric and the matrix sheet material have first and second ends and the first ends are located in the interior of the winding and the second ends are radially outwardly displaced from the first ends.
