Airbus Helicopters is replacing aluminum in a fitting in the aircraft door of the Airbus A350-900 with a high-modulus, carbon fiber-reinforced high performance polymer.  The brackets, now manufactured from Victrex PEEK 90HMF40, has been developed by Airbus Helicopters and is in serial production for commercial use after receiving the relevant component qualification. The successful substitution of metal has resulted in a 40% reduction in weight and costs. The injection-molded polymer solution replaces the higher cost manufacture of the bracket machined from an aluminum block.  The fiber-reinforced polymer (FRP) structure of the A350 XWB’s aircraft door uses an outer skin coupled with a bracing structure on the inside. A fitting, now manufactured from PEEK thermoplastic, connects the outer skin to points on the internal bracing structure. The two components form a box-type support structure to exploit the maximum geometrical moment of inertia.  By using the carbon fiber r...

Biodegradable drinking cups or vegetable wrapping foil: the bioplastic known as polylactic acid (PLA) is already a part of our everyday lives. And yet, PLA is not yet considered a full alternative to traditional petroleum-based plastics, as it is costly to produce. Researchers from the KU Leuven Centre for Surface Chemistry and Catalysis now present a way to make the PLA production process more simple and waste-free. Their findings were published in Science.  The bioplastic PLA is derived from renewable resources, including the sugar in maize and sugarcane. Fermentation turns the sugar into lactic acid, which in turn is a building block for polylactic acid. PLA degrades after a number of years in certain environments. If it is collected and sorted correctly, it is both industrially compostable and recyclable. In addition, PLA is biocompatible and thus suitable for medical use, for instance in absorbable suture threads. PLA is also one of the few plastics that are suitable for 3D p...

Celanese Corporation (NYSE: CE), a global technology and specialty materials company, announces the introduction of Celanese® Polyphenylene Sulfide (PPS) to the Japanese market to meet the demanding product quality and materials specification needs of automotive customers in the country.  “Celanese® PPS is a highly stable and durable polymer and is a primary reason why customers in the Japanese automotive industry, among others, specify parts made from this material,” said Hajime Suzuki, Celanese managing director for Japan. “We see tremendous growth potential for a PPS polymer solution, and we are excited to bring our technical knowledge, processing expertise and product offering to regional and global OEM customers who call Japan their home.”  Celanese® PPS is a semi-crystalline polymer often used to replace metals and thermosets in various automotive, electrical/electronics, aerospace, fluid handling, and industrial and consumer applications.  Celanese will offer the ...

The plant – which assembles the family of A319s, A320s and A321s – is officially open for business, with a skilled team of more than 250 Airbus manufacturing employees now at work on the first US-made Airbus aircraft.  In an anticipated ceremony in Mobile, Alabama, Airbus inaugurated operations at its first ever US manufacturing facility.  “The Airbus U.S. Manufacturing Facility enables us to grow our already significant presence in America – the largest single-aisle aircraft market in the world – and to be closer to our U.S. customers and key supplier partners. At the same time, the expanded industrial capacity gives us more flexibility to increase production across Airbus to meet global demand. The U.S. facility is good news for the overall Airbus enterprise, as this greater production capacity creates global growth opportunities across the company and throughout our supply chain.” said Airbus President and CEO Fabrice Brégier.  Airbus announced plans for the $600 mill...
