Frequently Asked Questions: Composite Tubing

What is a composite?

A composite is any material that’s comprised of more than one discrete material with different properties. Carbon fiber and reinforced concrete are both examples of a composite material. They both use a high strength core (carbon fiber / steel rebar) encased in a rigid binder (epoxy resin / concrete).

Why are there so many kinds of composite tubing?

Different composites are good for different uses. For example, carbon fiber is used when the strongest, stiffest, lightest tube is required. Fiberglass tubes are generally cheaper than carbon fiber and don’t conduct electricity. Kevlar tubes can be super lightweight and abrasion resistant.

How do I pick the best composite for my project?

Carbon fiber is the go-to option for high performance composite tubes. It’s the strongest, stiffest, lightest option available. Fiberglass is good if you need specific properties like electrical isolation or radio transparency. Our customer service team is always available to answer additional questions.

What about hybrid composites?

Hybrid composites combine the best properties of multiple composite materials. Carbon fiber and Kevlar hybrids offer the stiffness of carbon fiber with the strength of Kevlar. Ekoa and fiberglass hybrids have the strength, stiffness and low weight of carbon fiber with a unique aesthetic.
