    Carbon bottles

    I always wondered as to the fragility of carbon fibre air bottles, i was surprised when i watched this.

    They're not a pure moulded lump of carbon fibre, they're a composite made by wrapping a thin wall aluminium tank with the carbon fibre to add strength.
    Rather neat bit of engineering.

    Interesting video, id guess if you did that to a regular tank it would suffer catastrophic failure and completely burst open.

    Watching that, I don't think that is something I'd want to try

    It does give you confidence of how sturdy these tanks are - a 500fpe lead slug totally disintegrated on impact, that is a lot more than a drop in the car park and it's focused on a single point. I'm not surprised a .308 FMJ bullet pierced it, your looking at around 2300fpe at that range!

    Well fortunately there is an arsehole out there who will.

    If younwant.to see a real lemon head at work...google scuba tank guilotime. He built a french style guilotine for the valve.

    See those steel tanks fly like exocetes.........and dint forget to dodge the occassional one that comes.back at ya....

    so thats the release from a small 2L? tank, would hate to have a failure of a 12L one.

    Is there a calculation of stored energy of compressed air in tanks?

    Yes

    It ranges from...." ooh..that stung a bit" through to " has anyone seen my head...it was in my shoulders just before I shot my .308.....!!!!!!!"
