Coating systems for NGV composite cylinders. Final report, May 1994

Technical Report ·
OSTI ID:6682718
The report documents an investigation of acid-resistant coating systems that can be applied to composite storage cylinders used on natural gas vehicles. Two recent tank failures were likely caused by stress corrosion cracking of the composite overwrap. Cracking was probably induced by acidic compounds (battery acid) in direct contact with the cylinder's fiber reinforced plastic overwrap. A literature search, discussions with cylinder manufacturers, and laboratory materials studies were performed to identify potential coatings. This investigation also identified relevant test procedures for environmental and materials evaluations.
