Ericsson yachts Made Using ACG’s Carbon Prepreg Materials

8th April 2008 0 comments

Ericsson Racing Team’s boat ‘Ericsson 3’, which was unveiled to the yachting press on the 12th February, is the first one-off Volvo Ocean Race (VO70) challenge yacht to come out of the purpose-built Ericsson boatyard in Kista, Sweden. This is the first of two Ericsson yachts to be made using ACG’s carbon prepreg materials; Ericsson 4 is in the boatyard right now. ACG has its sights firmly set on providing Ericsson Racing Team with customised materials and technical expertise to support them in this formidable venture. With Juan Kouyoumdjian as the exclusive designer for Ericsson Racing Team, and Killian Bushe as construction manager, Ericsson 3 is one of a kind, embracing the strong heritage of the winning yacht ‘ABN AMRO One’, now ‘Ericsson 2’, a veteran of the 2005-2006 Volvo Ocean Race. One of the final steps in Ericsson 3’s construction process was to provide it with its true identity – adding colour to the sleek black carbon hull, the product of employing VTM264, ACG’s long out life, intermediate viscosity, epoxy resin matrix prepreg and its associated VTA260 film adhesive, which is used to bond the honeycomb and foam core . The first step in the construction technique adopted by Kouyoumdjian and Bushe was to build a plug, an outline of the hull, from precision-cut frames. Once the plug was made, a carbon fibre mould was built around it. The inside of the finished mould had to reflect the exact dimensions of the boat’s hull, so accuracy was of paramount importance. The hull was then fabricated in two layers, with honeycomb core or foam sandwiched between them to add stiffness to the structure. In areas where extra strength is required, such as around the keel, high density foam or solid carbon fibre was used. Once fully laminated, the hull was slowly cured in an oven. The Kista yard has two ovens, one at 26 metres long, just big enough to accommodate the entire boat. The second, smaller oven was used to cure the carbon fibre prepreg deck, bulkheads, galley, navigational station, and the toilet.

Flow International Corporation Receives Contract from Mitsubishi Heavy Industries

14th April 2008 0 comments

Mitsubishi Heavy Industries (MHI) has awarded Flow International a second multi-million dollar contract to supply MHI with Flow’s Composite Machining Center (CMC) waterjet machine tools to cut carbon fibre wing skins. Flow’s CMC waterjet machining system for carbon fibre composite wings will measure 118 feet long and 21 feet wide. The CMC will be utilized for cutting the composite wing skins which are part of the composite wing structure. The CMC system will be built and tested in Jeffersonville, Ind., one of Flow’s four worldwide manufacturing plants. The UHP pumps that provide the ultrahigh-pressure water will be made at the Kent, Wash. headquarters. “”The award of Flow’s second CMC commercial wing machining system proves the effectiveness of Flow’s waterjet technology and its ability to create ‘state of the art’ aircraft parts in a cost-effective manner,”” said Charley Brown, CEO of Flow International Corporation. Waterjets cut by erosive action rather than friction and shearing. To cut carbon composite aircraft parts, a thin stream of water moving at three times the speed of sound is emitted from a tiny, jeweled orifice in the tool head of Flow’s machine. The one gallon-per-minute water flow draws in a separate stream of fine garnet particles that slice into the surface being cut. They produce exceptional edge quality-free of frayed or delaminated areas, which minimizes costly secondary finishing. The waterjet’s low operating temperature doesn’t affect the material being cut. Furthermore, because waterjets exert less lateral force on the material than conventional machines, tooling and fixturing requirements are simpler and less expensive.

Diaphorm Develops Lightweight Combat Helmet

14th April 2008 0 comments

Using its proprietary quick-cycle moulding processes, Diaphorm Technologies LLC is now producing composite combat helmets that they say weigh up to 10% less than available ACH (Advanced Combat Helmet)-grade helmets. The company will also double helmet capacity to 50,000 units/yr by May, to meet demand for their growing helmet line. Diaphorm moulds the helmets of thermoplastic with ballistically-rated continuous fibre reinforcement. Current production volumes average 100 units/day. “The new combat helmet far exceeds ACH specs for impact, meets all specs for ballistic protection, and greatly reduces shock transference to the soldier,” says Bob Miller, Diaphorm president. It is marketed through Diaphorm’s subsidiary, Max Pro-Police & Armor. Diaphorm says that, in standardized ACH tests, the helmet transferred one third less impact to the dummy head than all other helmets tested. The shell of the new combat helmet is made with the same proprietary moulding process and similar construction as the company’s NIJ Level IIIa tactical helmets. “Demand has been so strong that it tapped out our current capacity,” said Mr. Miller. “The 100% expansion will happen quickly, will use the same proven process and process controls, and can produce both helmets.”

Consortium Introduces Composite Coating Based on Nanoparticles

14th April 2008 0 comments

The pan-European Foremost consortium has completed the development of its first composite coating, based on ApNano Materials’ inorganic fullerene (IF) nanoparticles. The new coating is being considered for plating advanced parts by some of Foremost partners and other industrial firms, to achieve improved efficiency, reduced emission, and extended equipment lifetimes in harsh conditions. The coating developed by Foremost has better lubricating properties than several commercially available ones tested under the same conditions, lasting tens of thousands cycles longer. The innovative coating was introduced in a meeting of the scientific and executive committee of Foremost (Fullerene-based Opportunities for Robust Engineering: Making Optimized Surfaces for Tribology), held in Israel in February. Foremost’s total budget is €18.9 million. It is funded by the European Union’s Sixth Framework Program for Nanotechnologies and Nanosciences, Knowledge based Multifunctional Materials and New Production Processes and Devices. The objective of Foremost is to provide radically improved coatings and lubricants to significantly reduce friction and wear in order to substantially save energy, extend operating lifetimes, reduce maintenance and reduce the environmental impact of machines, automobiles and trucks, and other modes of transportation. This project gives pan-European recognition of ApNano Materials technology and business. Foremost’s 31 members, in addition to NanoMaterials (ApNano Materials’ R&D company), include EADS, the parent company of Airbus, Renault-Nissan, the giant automobile manufacturer, Fuchs, the world’s largest independent lubricant company, Rolls Royce jet engines, and IonBond, among others. ApNano Materials’ fullerenes are particles of tungsten disulfide (WS2) that have a structure of nested spheres, called inorganic fullerenes, which lubricate mainly by rolling like miniature ball bearings. When used as an additive to liquid oil or grease, the nanoparticles significantly enhance the lubricating properties of the oil or grease with respect to wear and friction by an order of magnitude versus the same lubricant without this additive. “”We are proud that this distinguished pan-European consortium has introduced the new coating, based on our technology, which will contribute to the global efforts to save energy and reduce pollution,”” said Dr. Menachem Genut, President and CEO of ApNano Materials. Dr. Genut was a research fellow in the original research group which discovered the inorganic fullerene nanoparticles at the Weizmann Institute of Science, Israel, and first to synthesize the new material. The group was led by Professor Reshef Tenne, currently the Director of Helen and Martin Kimmel Center for Nanoscale Science at the Weizmann Institute. “”The achievement of the Foremost consortium, and the fact that its members include top European manufacturers, further demonstrate the commercial potential of our technology,” said Aharon Feuerstein, co-Founder, Chairman and CFO of ApNano Materials. “Foremost is another milestone in making the inorganic fullerenes a global standard for creating innovative lubricants and composite coatings that will highly reduce friction and wear and prolong machinery life,” said Dr. Niles Fleischer VP of Business and Product Development of ApNano Materials

In response to increasing demand for large pultruded products, Strongwell Corporation has increased its pultrusion capacity for these products in its Bristol, Virginia plant. Strongwell’s Machine Group designed and built a 60” wide, 40,000 pounds pull force machine in 2007. Production on this new machine began in January 2008. Strongwell’s new 60” pultrusion machine is capable of pultruding fiberglass plate up to 1” thick and 60” wide as well as large custom pultrusions such as sheet piling, custom designed wide panels, and various other wide profiles requiring large pulling capacity. The addition of this 60” wide pultrusion machine gives Strongwell five pultrusion machines capable of pultruding 48” wide to 60” wide profiles and plate. In February 2008, Strongwell also installed a new 36” wide, 40,000 pounds pulling force pultrusion machine built by Process Design Associates of Dayton, Ohio in its Bristol, Virginia plant. This large capacity pultrusion machine was added to Strongwell’s capabilities as a result of increasing demand for large custom pultruded profiles from the construction market and military market. The new machine is capable of pultruding Crane Materials International’s new 36” wide box style sheet piling as well as other large, heavy pultruded profiles. Strongwell expects the trend toward larger, more complex profiles for large infrastructure and commercial building projects as well as increasing demand for wide composite plates for various US Department of Defense programs to continue. Future pultrusion capacity additions will be implemented as market demand requires. http:// www.strongwell.com
