Fiberfrax?
Thinking of using Fiberfrax on cowling near exhaust pipes.
Has anyone used this material and if so, what thickness is recommended 1/16" or 1/8"? |

I am thinking of adding 1/8" to my firewall on a new build. It says 2000f temp. anyone used it in lieu of some of the other stuff tested by Dan H.? I don't recall him testing fiberfax.

Some good info in this thread:
http://www.vansairforce.com/communit...d.php?t=131516 I used morgan superwool HT. Pretty similar, but biosoluble if you breath the dust in when cutting. Bit more delicate, but got the job done. My process is described in page 7 of the above thread. http://www.vansairforce.com/communit...=131516&page=7 Tom. RV-7 |

I put 1/16" Fiberfrax on the firewall covered with stainless steel foil, seamed with Al tape; and the same 1/16" on my exhaust tunnel covered with .012 Titanium sheet seemed with Firebarrier 2000. I believe Dans test showed it does its job but does outgas when flamed, hence his recommendation was only on the engine side......thickness would be your call. I dont know any property differences.

I used 1/8" for the firewall and inside the tunnel and 1/16" for the cowl. |
Strips of fiberfrax to shadow the pipes, under the HD self-stick foil sold by Vans. If the interior of the cowl is finish painted, the foil sticks without any other glue.

I have the 1/16" Fiberfrax on my cowling. I ended up adding more after the first year of flying. You can see the discoloration from the heat.
Before: ![]() After: ![]() If I had it to do over again, I would have put a lot more down there in the initial application during the build. It has held up well and the paint on the exterior is still looking great. |
