This paper was aimed at the investigation of effect of the aluminum liner vices to the fatigue and burst
characteristics of the filament winding composite pressure vessels. These vices included hollowness, corrosion and
cracks on the metal liner. The results shown that the vices exited on the metal liner could lead to stress concentration,
which brought on cracks spreading along these vices. So the invalidation of the metal liner was advance of the composite.
All of those could stimulate more damages to the vessels, which lead to degrade final burst pressure and fatigue
cycling. These vices hereby gave rise to a great effect on final properties of the composite pressure vessels.
