The report details the results of simulated rain erosion testing done on Grummans CPI Closed Pore Insulation material to further demonstrate its suitability as a viable TPS material for NASAs shuttle orbiter. This program was done to assess the resistance of CPI to damage from rain that may be encountered during landing maneuvers following re-entry. This work indicated that while CPI was subject to some weight loss due to erosion, the material remained essentially waterproof during and after exposure, thus avoiding severe heat shield degradation due to excessive water pickup.
