Carbon Fiber fiber-reinforced polymer sleeves have recently received much interest from industries owing to their superior properties. One of the important applications of CFRP sleeves lies in electric motors of high performance. These sleeves, popularly known as bandages or tubes of CFRP, are somewhat superior to traditional materials in many ways because they enhance efficiency and performance and make electric motors even more durable. In this paper, we review the benefits of CFRP sleeves, their implementation in electric motors, and what difference they make to the efficiency of the motors. 1. What Are CFRP Sleeves? CFRP sleeves are composite materials manufactured by reinforcing carbon fibers with a polymer matrix. The combination of reinforcement produces a lightweight yet very strong material that features superior mechanical properties. The CFRP sleeves would wrap around such components as an electric motor rotor, adding structural integrity to it and generally improving its pe...
