Under Contract NAS8-27566, "Design and Development of Polyphenylene Oxide Foam as a Reusable Insulation for LH2 Tanks," PPO foam has been tested for mechanical strength, for the effects of 100 thermal cycles from 450K (350F) to 21K (-423F) and for gas flow resistance characteristics. PPO foam panels have been investigated for density variations, methods for joining panels have been studied and panel joint thermal test specimens have been fabricated. The range of foam panel thicknesses under…

A reliable lightweight insulation system is required for re-usable liquid-hydrogen-fueled vehicles such as the space shuttle, which is being designed for 100 to 200 launch and entry flight cycles. A
