What was the laminate schedule? It looks like 1 layer of bidirectional CF cloth, a foam (Divinycell?) and another layer of bidirectional CF. What weight cloth and foam type and thickness was used?
@@BobKuykendall That doesn't answer my question. Is it a trade secrete? I'm curious if it's a 5.7oz or 8oz satin, twill or plain weave and what type of foam and thickness was used. The answers would be most helpful with my powered aircraft project.
@@GrantOakes It's not exactly secret, but I'd rather not get into specifics here. For your powered aircraft you'll almost certainly want a more robust lamination schedule based on sound engineering principles. There's a lot of great content on composite design on homebuiltairplanes.com, and many engineers on the forums with a far more comprehensive understanding than mine. I'd recommend starting here: www.homebuiltairplanes.com/forums/forums/composites.8/
The top side of this part is actually inside the wing. We do the same process for the upper wing skin, then install the wing spar and control system, then we glue this part on to close the wing.
There is no direct contact between any steel or aluminum parts and the carbon fiber. Anywhere they come close there is an insulating layer of fiberglass.
