New 1:1 Adhesives from Plexus

27th November 2007 0 comments

Three New Plexus structural adhesives have been introduced to produce strong yet flexible bonds on composites and offer medium to long working times for large assemblies. Plexus say that they require little or no surface preparation and cure at room temperature to tough, durable bonds that withstand service temperatures of – 40° to 180° F. Two-part structural methacrylates dispensed manually or with standard meter-mix equipment, MA530, MA560-1, and MA590 are 100% reactive, non-sagging gels recommended for joining composite assemblies, ABS, acrylics, FRP, gelcoats, polyesters (including DCPD modified), PVC, styrenics, and vinylesters. They are intended for boats, trucks, buses, architectural ornamentation, wind turbine blades, and composite bridges and decks. MA530 has a working time of 30-40 minutes and fills gaps up to 0.70”. A 0.03” bond line achieves approximately 75% of its ultimate shear strength in 90-160 minutes at 74° F, according to preliminary testing data. It is available in ready-to-use 400-ml cartridges, 5-gallon pails, and 50-gallon drums. MA560-1 has a longer working time (55-70 minutes) and fills gaps up to 1.00”. It is recommended for large structures as well as small-part assembly where fewer workers are required. Fixture time for a 0.03” bond line is 220-240 minutes at 74° F. This adhesive is also recommended for certain metals and many other substrates. It is available in ready-to-use 400-ml cartridges, 5-gallon pails, and 50-gallon drums. MA590, with a very long working time of 90-105 minutes, was formulated for building large fibreglass boats but of course is acceptable for other applications. A 0.03” bond line achieves approximately 75% of its ultimate shear strength in 180-240 minutes at 74° F. Like MA560-1, this adhesive fills gaps up to 1.00” and is recommended for certain metals in addition to many other substrates. It is available in ready-to-use 400-ml cartridges, 5-gallon pails, and 50-gallon drums.

Alberta Hemp Provides Opportunity for Business and Consumers

27th November 2007 0 comments

A new $2.25 million project is looking at ways to use Alberta-grown hemp fibres and Alberta manufactured polymers to produce a biocomposite that is far more sustainable compared to conventional materials. “Products made from biocomposites include car parts, building materials and other consumer goods,” says Dr. John Wolodko, program leader at ARC. “Those types of products work as well as those made from conventional materials and they can have the added advantages of being lighter and less expensive. The ability of environmentally friendly biocomposites to compete with non-renewable products like fiberglass makes for a promising future for the industry.” Biocomposites are popular in Europe but the industry does not exist in Alberta. “We have the opportunity to take what they’ve learned in Europe, adapt the technology for Alberta and provide the foundation for a new industry,” says Wolodko. “This is another example of how the Alberta government is committed to growing Alberta’s bioeconomy,” says Doug Horner, Minister of Advanced Education and Technology. “This project has the potential to provide new opportunities for economic growth, particularly in rural Alberta” ARC’s biofibres development team is the largest of its kind in Canada, offering solutions from “first seed to final product.” ARC’s capabilities in producing, processing and creating advanced biocomposites from industrial hemp, flax, cereal crop and wood fibres are positioning the province to assume a lead role developing bio-industries in Canada and around the world. This project is financially supported by Alberta Advanced Education and Technology’s Unleashing Innovation Program, and Alberta Agriculture and Food. Industry partners include Naturally Advanced Technologies and AT Plastics.

Carbon Nanotube Manufacturing Technology Wins Nano 50 Award

27th November 2007 0 comments

NASA Goddard Space Flight Center’s method for manufacturing high-quality carbon nanotubes (CNT) has been named a winner in the third annual Nanotech Briefs Nano 50 awards in the Technology category. This award was be celebrated at the Nano 50 awards dinner November 14 at the NASA Tech Briefs National Nano Engineering Conference (NNEC 2007) in Boston, Mass. Judged by a panel of nanotechnology experts, the Nano 50 awards recognize the top 50 technologies, products, and innovators that have significantly impacted (or are expected to impact) the state of the art in nanotechnology. The winners of the Nano 50 awards are the “”best of the best””—the innovative people and designs that will move nanotechnology to key mainstream markets. “”My deepest gratitude goes out to the panel of experts at Nanotech Briefs magazine, as well as Goddard’s Innovative Partnership Program (IPP) Office, for recognizing this technology and its future impact,”” expressed retired Goddard innovator, Jeannette Benavides, who is presenting her award-winning technology at NNEC 2007. Until recently, CNT use has been limited due to the complex, dangerous, and expensive methods for their production. Benavides’s technology represents a simpler, safer, and much less expensive manufacturing method. The key innovation in the process patented by NASA Goddard is its ability to produce bundles of CNTs without using a metal catalyst. Most single-walled CNT (SWCNT) manufacturing methods—chemical vapour deposition, laser ablation, microwave, and high-pressure carbon monoxide conversion—use a metal catalyst to encourage carbon to grow in nanotube form without capping. Because Goddard’s process does not use a metal catalyst, no metal particles need to be removed from the final product, yielding a significantly better product in terms of quality and purity at a dramatically lower cost. Given their level of purity, the high-quality SWCNTs made using Benavides’s discovery are particularly well suited for medical applications, where metal particles cannot be present, as well as applications where high strength and electrical conductivity are desired, since high purity enhances these characteristics. Yet, they can be used in other applications as well. For example, SWCNTs made with this process could be integrated into a polymer to result in a fibreglass-type material that is as strong as steel but with one-sixth the weight. The commercial impact of this discovery is clearly demonstrated by the market’s significant interest in the technology. Goddard has licensed the technology to Idaho Space Materials, Nanotailor, and E-City NanoTechnologies, all of which were founded specifically to manufacture SWCNTs using Goddard’s technology. Goddard also has licensed the technology to American GFM. “”I’m very excited to see that the IPP Office’s licensing out of my technology is making CNTs more readily available, particularly for academic and other research programs. The fact that they now have access to lower cost CNTs bodes well for the future of nanotechnology,”” said Benavides. “”Dr. Benavides not only worked hard to develop the technology, but she also was very involved in the technology transfer process,”” explained the IPP Office’s Darryl Mitchell, who has led the licensing efforts for NASA Goddard. “”Her dedication has been essential to the success of the licensing agreements.””

Boats Built with Hexcel Composites Take Top Places in Transatlantic Race

27th November 2007 0 comments

Hexcel Corporation has congratulated skipper Michel Desjoyaux, co-skipper Emmanuel Le Borgne and the Foncia team on their victory in the Transat Jacques Vabre race. Congratulations were also extended to the Safran sailing team, skipper Marc Guillemot and co-skipper Charles Caudrelier on finishing in second place. Both boats, which set off from Le Havre, France on November 3rd and arrived on 20th in Salvador de Bahia, Brazil were built with composite materials from Hexcel. David E Berges, Hexcel’s Chairman and CEO said, “Everyone at Hexcel congratulates the Foncia and Safran teams on their tremendous performance. Our organization is excited to have contributed to this achievement. The lightweight but exceptionally strong Hexcel materials supplied for both boats are another example of our Company’s efforts to make everything from aircraft to racing yachts lighter, stronger, faster.” The Foncia boat, designed by Farr Yacht Design, was built by the Chantier CDK shipyard in France. CDK selected Hexcel composite materials due to their previous winning experiences and tried and trusted performance. The Foncia has a honeycomb sandwich construction and was built with both woven and unidirectional HexPly M10 prepregs, using high strength carbon fibre. The innovative design of the Safran monohull was conceived by leading marine architects Van Peteghem-Lauriot Prevost and Guillaume Verdier. Working to an extremely tight schedule, the team took four months to plan and design the boat with a view to building a high-tech carbon honeycomb sandwich structure, as lightweight as possible but strong enough to withstand single-handed sailing in the worst ocean-going conditions. The Chantier Naval de Larros shipyard, which specialises in the composite construction of boats, was selected to build the Safran. Materials selection was critical and, as preferred partner for the supply of composites, Hexcel took up the challenge and helped the architects optimize the choice of carbon fibers and composites, within the confines of the Open 60 restrictions. A range of HexPly M10 prepregs with woven and unidirectional reinforcements was selected. Hexcel’s carbon fibre was used extensively: HexTow IM7 very high strength carbon fibre was used for the hull and deck structures; while HexTow IM9 super strength carbon fibre was selected for the bow section and the hull. The Safran achievement is all the more outstanding considering the boat lost its large spinnaker on day 10 day of the race, resulting in a 15 degree wind angle loss in relation to the other competing boats. According to the skipper, Marc Guillemot: “This boat has so many assets and is state-of-the art. The extreme lightness and rigidity make it highly manoeuvrable, which is a major asset”. The Transat race was superb training for the Vendee Globe solo, round the world race that starts in November 2008, which has always been the main goal for the Safran team, and in which the two boats will again compete.
