At the point of making the firewall insulation choice.
I have the Dan Horton tests and recommendation.
I plan on following the basic idea on material choice.
- should not catch on fire
- should not produce toxic fumes or smoke
- should meet the 2000 deg requirement
Seems fiberflax had an issue of out gassing when under high temp or fire.
This leaves me with the cerablanket. ( now known as superwool 607). Will get this from McMastercarr.
So the last two issues are how to cover the superwool and how to attach it to the firewall.
My idea is to use Nomex fabric and thread to sew covers for the superwool. This will not survive over 600 deg, but the superwool will. The only reason for the nomex is to contain the superwool fibers. Would not want them in my lungs.
So this leaves the attachment method. Thinking of using screws and nutserts. This way when the Nomex desintegrats the superwoll will still be attached to the firewall.
I know this is going to open a lot of debate, but does anyone see an issue with my idea?
Should the insulation be separate sections between the angle aluminum, or cover the whole firewall in one piece?
