    carbon fiber

    Ok I was reading on this site: http://web.njit.edu/~cas1383/proj/FAQ/index.htm

    And He Said Laying Carbon Fiber And Fiberglass was the exact same...
    Has anyone had experience with laying carbon fiber? I was gonna make my sub enclosures out of fiberglass with a layer of carbon fiber over it to make it look nice, and was wondering how hard or easy this would be

    my dad has done it and he said its the exact same...
    why would you layer CF over fiber? why not just make it CF? i cant imagine it would take much more CF to make it strong enough.

    Because fiberglass is much cheaper, this would be similar to putting veneer over MDF instead of using sold hardwood, much more economical.

    first thing, make sure you use epoxy resin, not polyester. the epoxy is less thixotropic, and can wet teh fibers much better than polyester. the medium cure side B should dry the clearest, fast and slow cure will yellow slightly.

    I reccommend leaving a texture, rather than finishing glass smooth. itll lose the 3d nature of the carbon, but it will look totally awesome and be unique from liek a carbon hood or something.

    when you cut it, cut it WAY big, the fibers will jsut call out on teh edges. furthermore, dont even lay anything on the carbon. when I was cutting carbon, I laid the scissors right on the cloth, and hte hinge screw on teh scissors tore the carbon and put a permanent dimple in it.

    go out and get yourself a squeegee, itll make your job 10x easier. the carbon is a weave, so it will conform to compound corners. once dry laid, you can pour your epoxy on and spready it with the squeegee. always always always make sure its uniform, never ever do a thick layer of resin. you are jsut asking to get nonuniformities, and once you ahve to sand, you ruin the finish without boatloads of work.

    good call using it as a veneer, make sure your glass under is vinyl smooth, carpet smooth isnt good enough.

    and good luck!

    where does one buy the raw carbon fibre from ? and from my understanding of the process involved, the carbon fibre made the way fibreglass is made wont be as strong as carbon fibre made the way the professionals do it, in an autoclave
