Often used in place of aluminum for structural frames, machinery components, and robotics, these tubes are lighter in weight and almost as rigid.

Mount these lightweight half rounds on flat surfaces to reinforce frames and structures. Carbon fiber is often used in place of aluminum because it weighs less but is almost as rigid.

Often used for structural framing, machinery components, and robotics, these carbon fiber tubes are as stiff as steel yet a fraction of the weight.

Hard fiber is the easiest composite to machine, making it good for creating custom parts. Also known as vulcanized fiber.
