A&P Technology developed the design and manufacturing process for braided pressure vessels, achieving failure modes that exceed expectations. The preform allows contouring materials over the tank end-domes, application of hoop fibers through the cylindrical tank portions, and proprietary technology for the placement and application of materials.
With this approach the process cycle time is reduced to 30 minutes per cycle, significantly faster than alternate technologies.
Using the inherent interlocking of fibers in a braid architecture, failure modes were developed that are much more benign than those achieved with filament winding.
To date, work has been conducted on CNG tanks. Based on demonstrated capabilities this technology is now being used for the development of braided hydrogen tanks.
