  A revolutionary cryogenic tank design promises to radically boost the range of hydrogen-powered aircraft – to the point where clean, fuel-cell airliners could fly up to four times farther than comparable planes running on today's dirty jet fuel. Weight is the enemy of all things aerospace – indeed, hydrogen's superior energy storage per weight is what makes it such an attractive alternative to lithium batteries in the aviation world. We've written before about  HyPoint's turbo air-cooled fuel cell technology , but its key differentiator in the aviation market is its enormous power density compared with traditional fuel cells. For its high power output, it's extremely lightweight. Now, it seems HyPoint has found a similarly-minded partner that's making similar claims on the fuel storage side. Tennessee company Gloyer-Taylor Laboratories (GTL) has been working for many years now on developing ultra-lightweight cryogenic tanks made from graphite fiber composites,

  (Oslo, 21 April 2022) Hexagon Purus, a world-leading supplier of zero-emission mobility solutions, has entered into an agreement to acquire 40% of Cryoshelter GmbH’s (“Cryoshelter”) liquid hydrogen business. The transaction is in conjunction with Hexagon Composites’ acquisition of a 40% stake in Cryoshelter’s liquid natural gas (LNG) business. Cryoshelter’s liquid hydrogen tank technology is in the early stage of development and builds on superior and differentiated LNG technology that provides more fuel capacity and higher hold times (a critical requirement for cryogenic storage) than competing offerings. The transaction brings early-stage expertise in liquid hydrogen tank technology for zero-emission mobility applications and could potentially result in a future complimentary offering to Hexagon Purus’ market-leading compressed hydrogen cylinder technology. Key terms and structure of the transaction An initial investment of EUR 3.5 million for 40% of the shares in Cryoshelter’s liq

📢Time to Get Technical...📢 Tailored Fiber Plaplacement cement (TFP) is an embroidery-based tow-steering process that enables complete control over fiber and directionality in a composite preform. During the process, continuous tow is stitched to a backing material using numerical control. The result is highly engineered composite structures that take full advantage of the anisotropic nature of fiber reinforcement. Several fibrous materials like carbon, glass, basalt, aramid, natural, thermoplastic, ceramic fibers, or metallic threads can be placed in a near-net shape on a carrier material by TFP. Even the placement of different materials at the same time or one after another can be proceeded by TFP. Especially while using the TFP technology for the placement of carbon rovings to create preforms for composite parts, a high degree of freedom is an advantage. The rovings can be placed exactly according to the distribution of forces within a structural component. This leads to a higher f

 ( Oslo, 20 April 2022) Hexagon Purus, through its wholly-owned subsidiary, Wystrach GmbH (“Wystrach”), a leading hydrogen systems supplier, has received a follow-on order worth approximately EUR 1.5 million (approx. NOK 14 million) to deliver hydrogen distribution systems to a leading global industrial gas company. This order can be viewed in conjunction with the announcement on February 4, 2022, of a separate order with a value of approximately EUR 5.7 million (approx. NOK 58 million). Wystrach’s hydrogen distribution systems with Hexagon Purus’ type 4 cylinders will be used to deliver hydrogen for industrial and mobility applications in the Netherlands. Source:hexagon Purus

"Q Qarbon Aerospace has announced the completion and delivery of the first HEXA, LIFT Aircraft’s electric vertical takeoff, and landing (eVTOL) aircraft, produced by Qarbon Aerospace. HEXA’s carbon-fiber structure was manufactured at Qarbon Aerospace’s Thailand facility, with final assembly and integration performed in Red Oak." "Qarbon Aerospace is a provider of large, complex composite and metallic structural components, and assemblies such as fuselages, wings, flight control surfaces, and engine nacelles and components. Qarbon Aerospace operates nearly two million square feet of factory space across three facilities located in Red Oak, Texas, Milledgeville, Georgia, and Rayong, Thailand, with vertically integrated manufacturing capabilities from component fabrication through the large-scale assembly as well as proprietary thermoplastics technologies."

  After 26 years in business, Australia’s CST Composites is positioning itself to be a leading player in the global green hydrogen supply chain through a joint venture with US-based hydrogen storage tank manufacturer Optimum Composite Technologies. The joint venture will see CST Composites expand its core capabilities to support the growth of Optimum’s business in designing and producing Composite Pressure Vessels (CPVs), which are used to store hydrogen and Renewable Natural Gas (RNG) and have many other applications. CST has two manufacturing facilities in Australia and the growth plans include establishing Australia’s first hydrogen vessel manufacturing facility, which will service emerging and growing demand from the defence (e.g. VTOL vehicles), space (e.g. rockets), transport and energy sectors. This manufacturing facility will help advance Australia’s National Hydrogen Strategy, which highlights the need to develop the country’s supply chain infrastructure, including hydrogen st

  📢Time to Get Technical...📢 Let's learn more about the main properties of composite materials! As you may know, the characteristics/properties of composite materials resulting from the combination of reinforcement and matrix depend on the proportions of reinforcements and matrix, the form of the reinforcement, and the fabrication process. But what are the most remarkable properties of these materials? - Composite materials generally possess very high specific mechanical properties. - Composite materials do not yield: their elastic limits correspond to the rupture limit. - Composite materials have high strength under fatigue loads. - Composite materials age under the action of moisture and heat. - Composite materials do not corrode, except in the case of contact aluminum with carbon fibers in which galvanic phenomenon creates rapid corrosion. - Composite materials are not sensitive to the common chemicals used in engines: grease, oils, hydraulic liquids, paints and solvents, petr
