I was wondering why they seem to have never done it in carbon fiber also. Might just not be able to weave it correctly and get the spring back.
So far I found some large rolls on Ebay that work out to about $18/yard, but it is the 1/2" thick stuff that is probably too thick for anything I would want to do with it. Sounds high, but when compared with multiple layers of glass and a core material it might not be that bad. They make it from 3mm to 22mm thick. I would think the 3mm would be best for something like a cowl or wheel pants and something in the 1/4" range would be good for something like wing skins. I sent a request on the web site for some samples and more info. I will let you know what I find out. Sam said that he does not know of anyone else using it. I would think that it would have limited use for homebuilders except when used in a mold. -------- Original Message -------- Subject: Re: KR> Parabeam 3D fabric From: "Mark Langford" <ml at n56ml.com> List-Post: [email protected] Date: Sun, February 09, 2014 8:45 pm To: "KRnet" <krnet at list.krnet.org> Brian Kraut wrote: > Supposedly the resin goes to the outside layers and leaves an air space > in the middle so it winds up like a foam or Nomex core material that is > light and very strong. Mark Lougheed and I looked at Parabeam back in the 90's, and it was impressively strong but lightweight, but also very expensive. Let me know when you find a price. I haven't heard anything about it lately (it was new back then), so I figured it's been displaced by carbon fiber on Nomex, but it probably has a niche with homebuilders...
