Nasa: Why not sheath the underbelly of the shuttle with carbon?

Question

fiber/kevlar layer so that it would protect it from shrapnel at takeoff and then either burn off or not hinder the function of the heat tiles on re-entry?

Answer 1

they already do

Answer 2

Hmm, interesting thought, and if not Carbon could build a "Burn off shield" that would not survive the re-entry, but would keep the underbelly of the shuttle from getting damaged at lift off. Not a bad idea actually.

Email it to NASA? Posting it to Answers won't help them too much, unless they read Answers too?

Answer 3

I agree with andres r I didn't get a response for my idea but I sent it to nasa. alternative pollution fuel reactions( based on nature slightly)
