@IRStuff - Sorry about that

@SWComposites - Please have a look at the above answers for your questions and please share your thoughts

Thanks & Regards

The need to be a fire barrier probably rules out composites, though it depends on the specific fire regulations and requirements that need to be complied with.
Also, the low number of aircraft also probably rules out composites due to tooling costs.
So a metal design is probably appropriate. Machined frames/stiffeners riveted to sheet metal skin would likely be first choice. Material selection probably depends on fire requirements.

Thank You for your response.
I found few images in google, any idea how they might be formed/constructed. I'm very interested to know about 1st image (Engine Bay-1). I didnt see any support frames for this type. How that would be possible? OR was structural frame covered with a thin sheet?

And for second image, I can see some semi structure frame and other part is covered again.

Please suggest.

Thanks & Regards
