A lightweight, high-strength rotating component typically found in automotive and other mechanical power transmission systems, constructed from a composite material consisting of thin, strong carbon fibers bound together by a resin matrix. This component transmits torque between a power source (such as an engine) and a load (such as wheels or a propeller).
The inherent lightness coupled with exceptional torsional strength offers significant advantages over traditional metal counterparts. Reduced rotational inertia improves acceleration and fuel efficiency. Higher stiffness minimizes power loss due to twisting and allows for smoother operation. These composite shafts have become increasingly prevalent in high-performance vehicles, motorsport applications, and aerospace engineering where weight savings and efficient power transfer are paramount.
