Composite pressure vessel assembly and method of manufacturing

A composite pressure vessel assembly comprising:

• a first vessel including a first liner defining a first chamber, and a first mid-layer substantially enveloping the first liner;
• a second vessel including a second liner defining a second chamber, and a second mid-layer substantially enveloping the second liner, and wherein the first and second vessels are aligned side-by-side with a portion of the first mid-layer in contact with a portion of the second mid-layer, wherein each of the first and second liners include a lobe having at least one interior wall and at least one curved wall;
• an outer layer being in contact with and substantially enveloping the first and second mid-layers except for the portion of the first mid-layer in contact with the portion of the second mid-layer;
• and
• a plurality of junctions disposed where the respective ends of the curved walls and interior walls of the first and second liners meet, wherein the plurality of junctions are enveloped by the outer layer,
• wherein the outer layer is concave relative to an exterior of the pressure vessel at a meeting of a first interior wall of the first vessel and a second interior wall of the second vessel;
• and
• wherein the first and second mid-layers are made of a first composite comprising resin and a material selected from the group comprising continuous fiber wrapping, winded filaments, and a mixture of continuous and non-continuous fiber;
• and wherein the outer layer is made of a second composite comprising sprayed chopped fiber and resin upon the first composite of the first and second mid-layers, wherein the first composite differs from the second composite.
