Who We


The Missouri native’s love for carbon fiber first took off when he was racing sprint cars on the World of Outlaw tour at the age of 17. After 3 years on tour, he spent the next 5 years as a car chief mechanic with Buch Motorsports as well as Jason Johnson Racing. Clyde was always so intrigued with the looks and weight of certain body panels on these sprint cars, he discovered these panels & parts were made out of 100% carbon fiber. 

With carbon fiber coming into the dirt racing scene around 2010, not a lot of competitors ran it because of the cost. Regardless of the price, Clyde studied the durability of carbon fiber and observed how it held up during a heavy loaded racing schedule. Turns out, carbon fiber lasted 10x longer than fiberglass not to mention it’s far more attractive to the eye of the racer. With carbon fiber being the clear winner, Clyde dug more into the process to find out how it could be produced for a reasonable price. With the purpose of putting ideas in action, Prime Composites was born! We now build and provide carbon fiber bodies for race teams across the United States & around the world.

Are you wondering what the heck carbon fiber is? Well you see carbon fiber is everything you’d want in a material. With its high strength to weight, stiff strength, high temperature tolerance, carbon fiber is some tough, badass stuff. 

Mastered in aircraft, designed for racing, & approved for marine & military grade equipment, carbon fiber will suit every need for a light, strong, & attractive component. 

So you’re probably still wondering what carbon fiber is, right? Well it’s science. 

Several thousands of carbon atoms are bonded together in crystals, bundled within to form a tow which then is woven into a fabric/reinforcement. That fabric is laid into a mold with epoxy resin, vacuum bagged, & heat treated  to then form your application. Once demolded, we trim to spec, packaged safely, & shipped to your door!
