Design and Analysis Techniques for Filament-Wound Composite Pressure Vessel Domes

The use of filament-wound composite pressure vessels has expanded into many new markets in recent years, creating the need for better design and analysis techniques, particularly for the end domes. In this paper, design and analysis techniques are developed for elliptical-conical dome profiles with planar filament winding patterns. The effects of wide winding bandwidth are included by dividing the band into sub-bands and considering any point on the dome contour to be a laminate made up of the sub-bands. The slippage tendency of the band at its edges is also calculated.
