Filament winding has proven to be a viable manufacturing technique to produce composite overwrapped pressure vessels (COPV) for use in space applications. This technique incorporates winding of composite prepregs tapes over a thin metal shell followed by curing. Simulation of this manufacturing process and subsequent assessment of vessel durability and damage tolerance (D & DT) is a computationally challenging task, which requires progressive failure analysis (PFA). This demanding task can be accomplished using GENOA Progressive Failure Analysis (GENOA-PFA), a tested virtual design/analysis software capable of simulating progressive failure of composite structures in a variety of situations. A GENOA-PFA module simulating the manufacturing process for COPVS has resulted in integration of manufacturing, progressive failure, and probabitistic analysis into a robust software package, GENOA-COBSTRAN. GENOA-COBSTRAN has been used to simulate the manufacture and pressurization of a filament wound cylinder c onsisting of an aluminum 6061-T6 liner overwrapped with graphite- epoxy composite. The result of the simulation are presented and show 1) the failure pressure, 2) damage progression and 4) locations and failure modes of failure.
