Abstract : A combined analytical and experimental effort was conducted to characterize dome reinforcement requirements for intermediate modulus (30-34 msi) carbon/epoxy pressure vessels and evaluate the effects of shallow dome profiles on their performance. The study demonstrated that spiral-wound wafers are effective reinforcements to prevent boss blowout. Also, carbon, because of its superior stiffness-related properties over other fibers, allows low dome profile pressure vessel designs wherein dome failure becomes compressive buckling related. Although the test indicated that no performance advantage is apparent with the shallow dome shape because of increased case weight and reduced pressure vessel burst strengths, the low dome shape may be desirable in special applications where maximum propellant volume is the primary design objective.
