Abstract
A method of manufacturing a composite vessel assembly includes the step of placing the composite vessel assembly in a pliable containment prior to curing of a resin of the composite vessel assembly. With the composite vessel assembly in the pliable containment, a vacuum is applied through an orifice in the pliable containment to evacuate air and compact the composite vessel assembly.
