CNG Storage / Pressure Vessels Applications

ZOLTEK carbon fiber has been at the forefront of the evolution of pressure vessels and tanks for many years. The benefits of carbon fiber as a light-weight alternative to other materials makes combined with its durability and corrosion resistance properties have been driving innovation in these applications for decades.

Filament Winding

Filament Winding is the process of winding resin-impregnated fiber or tape on a mandrel surface in a precise geometric pattern. This is accomplished by rotating the mandrel while a delivery head precisely positions fibers on the mandrel surface. By winding continuous strands of carbon fiber in very precise patterns, ZOLTEK can build structures with properties stronger than steel at much lighter weights. Typical applications include Compressed Natural Gas (CNG) and Hydrogen Tanks.

With over 50 years’ experience, Engineering Technology Corporation (a ZOLTEK company) is the world’s leader in filament winding machinery and software. This expertise has allowed us to create FiberGrafiX™, a superior software application for winding pattern generation and optimization.Twenty years ago, this software program was the first of it’s kind.Today, FiberGrafiX has continued to lead the industry and is now used on more machines around the world than any other similar application.Patterns generated by FiberGrafiX can be output to any filament winding machine’s computer control system.
