摘要： A composite spring made of a wire of a longitudinal axis curved around a spring axis in a winding direction and a method of fabrication thereof, the spring, the wire comprising a core; and fibers layers wound around the core, and an angular positioning, relative to the spring axis, of each one of the fiber layers being selected, along a length of the core, depending on the winding direction of the wire about the spring axis, to adjust at least one of: high natural frequency of the spring, resistance to buckling and resistance to tensile and compressive stress components induced by a compressive load on the spring.
