Description:

• AETB-12 is a relatively low density (~12 lbs/cu.ft.), low thermal conductivity fibrous insulation material with higher temperature capability and better processing dimensional stability than the FRCI-12, LI-900 and LI-2200 insulation that are baselined on all of the shuttle orbiters. It was successfully flown on the shuttle at moderate temperatures as an experimental material on the top of the body flap.
