Automotive & e-Mobility Applications

Carbon Composite Shafts & Sleeves for Electric Motor Systems B&T Composites designs and manufactures high-performance carbon fiber shafts and sleeves used in next-generation electric drivetrains.

Our carbon sleeves are engineered to prevent magnet delamination and centrifugal failure at high rotational speeds,ensuring optimal durability and efficiency in high-speed electric motors.

Our components contribute to lightweight construction, high stiffness, and thermal stability — essential features for automotive OEMs and e-mobility system integrators.From rotor reinforcement to torque transmission, B&T supports the transition toward cleaner and smarter mobility.

1. Driveshafts and Propeller Shafts

Lightweight carbon fiber shafts for high-performance and electric vehicles (lower rotating mass = better efficiency).

2. Battery Enclosures

Composite housings for EV batteries — strong,

lightweight, thermally insulating.

3. Motor Casings / Housings

Composite casings for electric motors to reduce overall vehicle weight while maintaining strength.

4. Rotor Sleeves (for electric motors)

Which you already mentioned — essential for high-speed electric motors to contain magnets.
