  • Method for producing a monoblock composite connecting rod by placing preimpregnated fibers on an extractable mandrel and connecting rod obtained thereby
    Patent number: 6202505
    Abstract: Method for producing a connecting rod, particularly a monoblock composite connecting rod, and the resulting connecting rod is provided by placing preimpregnated fibers on an extractable mandrel, with the following successive stages. Embodying on a rigid central shaft a meltable mandrel with a shape corresponding to that of the connecting rod; winding and/or laying down the preimpregnated fibers according to a predetermined number of layers and an inclination of the fibers with respect to the longitudinal axis of the mandrel; polymerization with a homogeneous compacting pressure being applied to the entire outer surface of the unit; and then final operations for removing the mandrel and machining to required dimensions of the connecting rod.
