Carbon Fiber Tube - Unidirectional - 1/8" ID x 3/16" OD x 4 ft. Long

Unidirectional carbon fiber has its fibers running in a single parallel direction so it is ideal for applications where front-to-back strength is important. long, tubular structures that move in a forward-and-reverse direction, such as rockets, airplanes, boats, and bicycles, all use unidirectional carbon fiber as reinforcement.
