The potential for use of cryogenic fuel in aviation and ground transportation industry is growing, and along with it, the need for light-weight tanks to store liquid & sub-cooled hydrogen. Fiber-reinforced composite materials, especially, carbon-fiber composites, are widely used in aerospace industry and have replaced Aluminum, Steel and in some cases Titanium in airframe and engine...
As the aviation industry moves toward decarbonization, liquid hydrogen (LH2) emerges as a promising alternative fuel, offering the potential for zero carbon emissions during combustion. However, the successful use of LH2 in aircraft systems relies on understanding the structural integrity of composite materials under extreme temperature conditions as LH2 boils at 20 K (-253 ºC). The tensile...
Type-V cryogenic storage tanks, made from composite materials, have recently utilized 3D-printed composites reinforced with short carbon fibers. These materials combine lightweight design with excellent structural integrity while also exhibiting electrical conductivity and a piezometric response under applied loads. Despite these advantages, their piezometric properties remain unexplored,...
Maritime shipping of vast quantities of liquid hydrogen (LH2) will be necessary to facilitate a global hydrogen ecosystem; with some studies estimating volumes up to 172,000 m3 for individual tanker ships, and requiring stationary storage tanks at terminals of 50,000 m3 to 100,000 m3—ten to fifteen times larger than the current largest tank, located at launch pad B at NASA Kennedy Space Center...
As space exploration becomes more prevalent, passive thermal control becomes increasingly necessary. Preserved cryogenic compressed fuels in space for exploration must be exposed to as little thermal energy as possible, and the primary objective to accomplish this task is through the reflection of incident sunlight. Current passive reflective thermal control coatings are metallic with...
