Abstract
The moisture or water vapor barrier protection of a composite pressure vessel suitable for use as a composite cased solid propellant rocket motor is improved by immersing the pressure vessel, during pressure testing thereof, in a curable liquid polymer solution, optionally containing electrically conductive material such as metallic flakes or powder, so that the solution may flow into open voids, cracks or fractures in the pressure vessel and subsequently curing the curable liquid polymer in said voids, cracks or fractures.
