Ultra-Strength Lightweight Carbon Fiber Round Tubes

Often used in place of aluminum for structural frames, machinery components, and robotics, these tubes are lighter in weight and almost as rigid. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital. Thanks to these tubes being lightweight, they reduce wear and stress on motorized parts to extend the life of machinery.

Plain matte tubes have fibers that run in one direction, making them strong in the direction of the fibers. They resist bending across the fibers but will splinter and separate like string cheese when bent along the length of the fiber. Plain glossy tubes and checked tubes have layers with fibers that alternate in two directions, so they resist bending and crushing across the entire tube. They have more structural integrity compared to plain matte tubes.

Checked carbon fiber has the classic carbon-fiber look and is easy to machine—it won’t fray or splinter when cut. Glossy carbon fiber has a shiny finish that can be sanded to matte. Matte carbon fiber is ready to paint and won’t reflect light, making it ideal for photography applications.

Fit these lightweight tubes inside each other to create adjustable tubes for structural framing, machinery components, and robotics. Their hex shape prevents these tubes from twisting when they’re inside larger tubes and allows you to mount them to flat surfaces. Carbon fiber is often used in place of aluminum because it weighs less but is almost as rigid. It is known for its use in the aerospace industry where a balance of weight and strength is critical. These tubes reduce wear and stress on motorized parts and increase the life of machinery since they're lightweight.

These tubes have layers that alternate fibers in two directions, so they resist crushing across the tube. This checked carbon fiber is easy to machine—it won’t fray or splinter when cut. It also has the classic carbon-fiber look. The surface is glossy and can be sanded for a matte finish.

Ultra-Strength Lightweight Carbon Fiber Square Tubes

Color: Black
Temperature Range: 0° F to 250° F
Tensile Strength: 120,000-175,000 psi (Excellent)
Fiber Tensile Stiffness: Standard (33-36 msi)
Impact Strength: Not Rated
Hardness: Not Rated
For Use Outdoors: No

Mount these lightweight tubes to flat surfaces in place of aluminum to create structural frames, machinery components, and robotics. This carbon fiber weighs less yet is almost as rigid as aluminum. Adopted by the aerospace industry, carbon fiber is known for its balance of weight and strength. And since it's lightweight, it reduces the wear and stress on motorized parts, extending the life of machines.

These tubes have layers that alternate fibers in three directions, so they spread out their strength and resist crushing along the entire tube. They are checked, so they won’t fray or splinter when cut, making them easy to machine. They have the classic carbon-fiber look.

For Use Outdoors: No

Often used for structural framing, machinery components, and robotics, these carbon fiber tubes are as stiff as steel yet a fraction of the weight. Carbon fiber is known for its use in the aerospace industry where a balance of weight and strength is vital. Because they are lightweight, they reduce wear and stress on motorized parts, which increases the life of machinery. These tubes are constructed with layers that alternate fibers in two directions, making them difficult to bend.

The checked pattern on these tubes keeps fibers from splintering when the tubes are cut, making them easy to machine. It also has a classic carbon-fiber look. These tubes are glossy and can be sanded for a matte finish.

These rectangular tubes are flame retardant, machinable, and electrically insulating. They’re made of epoxy resin, making them good for use with printed circuit boards, insulating washers, and transformer components. With low moisture absorption, these tubes are often used as thermal insulators. Made with fiberglass fabric reinforcement, they’re strong and easier to machine than other glass cloth phenolics. Garolite G-10/FR4 is also called epoxy-grade industrial laminate and phenolic.
