About Composites

Ultra-Strength Lightweight Carbon Fiber Round Tubes

Made of carbon fiber, these are the strongest composite round tubes we offer. Carbon fiber is comparable in strength to 6061 aluminum yet lighter in weight. These round tubes are often used to build frames and structures.

Tubes with a 0° construction layup have fibers that are aligned in a single direction for linear strength and rigidity. They resist bending but will crush easily if impacted. They’re often used to support structures.

Matte tubes don’t reflect light and can be painted without any prep work. They’re often used in photography applications.

Electrical-Insulating Garolite XXX Tubes

Color: Brown
Maximum Temperature: 245° F
Tensile Strength: 8,700 psi (Good)
Impact Strength: Not Rated
Hardness: Rockwell M110 (Extra Hard)
For Use Outdoors: Yes
Specifications Met: MIL-I-24768/10

More electrically insulating than Garolite XX, these tubes are often machined into insulating washers, bushings, transformer spacers, and parts of terminal boards. Made of phenolic resin with paper reinforcement, they’re lightweight yet strong. While not as strong as Garolite XX, they absorb less water, so they work well in humid environments. These tubes won’t split during machining. They also won’t wear down tooling as fast as phenolic products with glass cloth reinforcement.
