The ultimate alternative to carbon fiber

Why Coyote Composite?

Several years ago, we made the switch to using basalt braid (Coyote Composite) rather than carbon fiber for our laminations. We initially did this for a more flexible, tougher lamination but ended seeing many other benefits as well with the main ones being that it's a much safer material that doesn't itch the way carbon fiber does and it costs a great deal less.

  • Extremely durable

  • Resistant to cracking

  • Less itch than carbon fiber

  • Non-carcinogenic and non-toxic

  • Strong and lightweight

  • Finishes smooth with superior resin saturation

  • Unique dampening characteristics

  • Less expensive


"Coyote Composite is definitely tough enough to keep up with me & everything I do."

Nick Edinger, "World's Strongest Adaptive Athlete 2016"



Our proprietary braid was designed to be used in equivalent amounts to carbon. Coyote Composite is more flexible than carbon (we consider this to be an advantage), but if you need to match the rigidity of a carbon socket, use additional layers of stockinette and/or carbon tape.

Coyote Composite fabric sheeting can be used for reinforcement layers of heavy duty sockets and/or AFOs. The material is thin and lightweight, which allows for greater flexibility in adding the ideal amount of reinforcement.

We use Coyote Composite rope as a reinforcement material in place of (or in conjunction with) carbon tape. This can be used for distal reinforcement or spot reinforcing in windowed sockets.

Important Details

RESIN: Coyote Composite works with typical prosthetic resins and saturates much better than carbon

SATURATION AND LAMINATION: Because of its superior saturation it's important to prevent resin starvation. Lamination starvation will cause frayed edges

FINISHING: Coyote Composite finishes easily except in cases of starved laminations. Use sharp tooling at slow speeds to finish. In some cases, you may need to wet-sand

RELIEVING: Coyote Composite is heat and flame-resistant and isn't damaged by heat. This allows for LIMITED adjustment based on the type of resin used

SAFETY: Because of the inert  nature of basalt, it is not a carcinogen. Also, Coyote Composite is between 9 - 16 micrometers in diameter, which is too large to be an inhalant risk. Basalt also causes significantly less skin irritation
