Carbon fiber suppressor

[TomMcC]

I don't know much about suppressors, but this looked interesting.

I wonder if this isn't the way to go with some of the lower pressure applications. I would think it'd be a slam dunk with 22lr, but I wouldn't know.

In the early 1980s I remember 2 liter soda bottles working "good enough" for a magazine of .380 out of a M11. It's not very hard to tame .22 lr but I worry that excessive exposure to heat would undermine anything made of polymer or similar materials.

This. Not much detail, but ut sounds like the tube is thin Al alloy with a CF wrap to reinforce it.

Interesting concept, Im curious what the limitations are vs “standard” aluminum-tube pistol silencers.

It probably improves hoop strength while letting the aluminum sleeve take the abuse. (I'm assuming hoop strength is the correct term.) With various metals being selected for the sleeve, I wonder how much you can get away with while still saving weight.

Well here is the problem, metal expands, which is why all the parts that get really hot on a Glock are still metal.

So if the shell is polymer, the baffles will expand with heat and crack the shell. If the baffles are polymer they probably won't last a week.

This isn't the first time somebody came up with the "disposable" suppressor concept but the $200 NFA tax makes such ideas impractical for US shooters. I'd rather pay $200 to register an oil filter.

I don't think they'd go so far as to use non-metallic baffles. But I'd be willing to bet you can find a way to get the carbon fiber sleeve to deal with it. 10 years ago I watched fiberglass parts being constantly destroyed in my industry as they designing one part that could take the force imparted into a spinning wheel. Tens of thousands of dollars of prototypes destroyed. Now they use them in some applications. Enough money being thrown at something, and someone often finds a way. How useful/tough/durable may be a different story.

But what would be the advantage? How much can a carbon fiber sleeve achieve in weight savings vs. the light metals already in use for things like .22 lr?

[opngrnd]

No practical advantage I can think of. But if people will buy it, they'll build it

I don't see it used for a hard use "firearm" suppressor but in the airgun circle that is already being done. With that I'd bet some of the engineers that are here might know of some carbon fiber formulas that are up to that. Think of the carbon fiber wrapped rifle barrels that are out and in use. The capability to manufacture them is out... for the jacket in fact. The more I think about it, it might work well for attenuation to cut the higher pitch noise that some really dislike.
With that $200 stamp I'll stick with proven tech... metal for now.
