In this video, we put a carbon fiber barrel to the test, firing 1000 rapid rounds to gauge its resilience under extreme heat. We use a bore scope for an in-depth examination after cutting the barrel clean down the middle, offering a unique inside look.

MDT was born out of a single purpose: to provide better value and better accuracy for precision rifles. The first MDT chassis was developed from the ground up based on the needs of shooters.
Our engineers verified every function and feature based on the input from competitive shooters. The end result was a game-changing product called the TAC21 that continues to perform at the range, in the field and in competitions around the world.
Today, MDT chassis, magazines and accessories are still developed the same way.
We collaborate, question and verify our concepts with precision shooters from around the globe to ensure that every MDT product is designed with the same single purpose: to provide our customers with the absolute best product possible.

Just a note, the carbon fiber not melting the snow isn't necessarily meaning it's not as hot but may just be because carbon fiber is a worse conductor of heat than the metal. Conductivity of the carbon fiber is probably variable based on the type of resin used, in this case looks like it's more insulative.

@@kh8655Not remotely. It's not about how much energy a thing has, but how readily it transfers that energy. Here's an analogy that might help. The difference between tannerite and C4 is how reactive they are. You can't detonate C4 (RDX) with regular methods. You can set C4 on fire and shoot it with a rifle and it won't detonate.

Two key factors can have big impacts to CB barrels: 1, overall thermo conductivity of carbon part: include characteristics of resin, filler and types of carbon fiber; 2nd, carbon to steel ratio. The alloy formula of steel also plays a good part in it too.

@rkwjunior2298 Жыл бұрын

Clearly the Carbon to Steel ratio was admirable in this test.

@cr0ss0ut Жыл бұрын

Also and possible more importantly, the way the barrel is wrapped. Proof Research (used in the video) spins individual carbon fiber strands around the barrel to build up the OD then grinds it back down to contour. Most other companies like Christiansen Arms Wraps their barrels with Woven CF sheets. In theory woven sheets will have much worse thermal dissipation. and, from an engineering standpoint, while being cheaper, is also the incorrect use application. Saving you the science / engineering talk, Proof does it correctly.

It's not necessarily that the carbon fiber isn't as hot, it's just that it's not conducting the heat as quickly. Steel is really low in thermal conductivity for metals down in the 15 to 45 W/m-K range depending on the particular alloy. Carbon fiber from what I've been able to find ranges between 6 and .4 W/m-K though due to the nature of composites, that's a lot harder to find good information on.
