Abstract

This article analyzes the possible causes of damage (cracking) of polymer materials used for the manufacture of composite cylinder liners and assesses the reliability of LPG storage cylinders of this design of polyethylene terphthalate. The principal difference between the existing LPG cylinder designs of different manufacturers is the design of the outer protective casing and the inner sealing liner for the composite (fiberglass) shell. It is shown that main causes of cracking in polyethylene terephthalate are technological and operational factors.
