A composite storage tank may include a wall structure including at least three regions including an inner region, an outer region, and at least one permeation barrier. Another region may be optionally incorporated for venting potential permeation of fluids. The at least one permeation barrier and/or the venting layer may be strategically positioned between the inner region and the outer region to reduce or at least partially prevent fluid permeation of the inner region or the outer region. A vehicle may include such a composite storage tank. Methods of forming a composite fluid storage tank may include forming an inner composite region, applying a permeation barrier to an outer surface of the inner composite region, forming an outer composite region, and curing the inner composite region and the outer composite region with the permeation barrier to form the composite fluid storage tank.

A tank suitable for storing a product at a cryogenic temperature, including a fluid tight interior barrier, a fluid tight exterior barrier, surrounding the first interior barrier, an intermediary volume interposed between the interior and exterior barriers and at least one insulating layer positioned in the intermediary volume and including at least one thermal insulation mat, with very low thermal conductivity. The intermediary volume contains microspheres outside of the thermal insulation mats and has an enhanced level of vacuum. This solution makes it possible to maintain satisfactory performance in terms of thermal insulation even in the event of a loss of vacuum in the intermediary volume.

Pressure vessels formed from fiber composites are described. The fiber composites include fibers impregnated with a resin system containing surface-modified nanoparticles dispersed in a curable matrix resin.

Provided herein are polymer matrix composites, articles including the polymer matrix composites, and methods of forming the polymer matrix composites. The polymer matrix composite includes a stitched composite and a hybrid barrier layer incorporated within the stitched composite, the hybrid barrier layer including a thin ply and a nanographene dispersed resin. The article includes a high-pressure composite cryogenic tank including the polymer matrix composite. The method includes positioning a dry thin ply between composite plies, stitching the composite plies to form a stitched preform, dispersing nanographene into the resin, and infusing the stitched preform with the modified resin.
