Abstract
A high pressure vessel construction in the form of an elongate tank includes a plurality of layers of resin impregnated graphite fibers and a plurality of layers of a hybrid of resin impregnated glass and polymer fibers, with the glass and polymer fiber layers alternating with the graphite fiber layers. The outermost layers are hoop wound and the innermost layers are helically wound. A layer of elastomer material is joined to the interior surface of the innermost layer of fibers, and a layer of stiff composite material is joined to the interior surface of the elastomer layer.

A high pressure vessel construction comprising
- an inner layer of resin impregnated graphite fibers wound to form an enclosure, and
- an outer layer hybrid of resin impregnated glass and polymer fibers wound about the inner layer and adhered thereto.
A high pressure tank comprising
- a first layer of high modulus, high strength fibers wound to form an enclosure having a generally circular cross-section, and
- a second layer of low modulus, high strength intra-ply combination of two types of fibers wound about and joined to the first layer.
