45 CompositesWorld.com CAMX 2017 Fiber-to-metal fastener solutions L&L; Products (Romeo, MI, US) is introducing its latest technology, Torque Retention, Isolation, and Sealing Solutions, an expandable, polymeric sealant material with embedded alumina rigid, nonconductive spacers that provide a direct load path to maintain fastener clamp forces. L&L; says this technology is unique because it allows torque retention, isolation and sealing simultaneously. The product is currently being implemented in the automotive industry to promote lightweighting by allowing carbon fiber-to-metal as well as metal-to-metal joining without the concern of corrosion caused by the formation of galvanic cells. In addition, it is said to be effective for sealing door, hood and liftgate hinges. L&L; Products' latest sealing solutions are either dry to the touch or tacky and can be heat-bonded, adhered to an interface surface or mounted directly to a bolt. The technology is designed and engineered using 0.5-mm or 1-mm diameter spheres embedded in sealing material and achieve less than 3% torque fall off. Booth B23. www.llproducts.com Cutting tools for carbon fiber composites LMT Onsrud LP (Waukegan, IL, US) is launching an all-new line of four diamond film-coated cutting tools designed specifi- cally for laminated carbon fiber materials. The new tooling series was created to reduce/prevent delamination of carbon fiber layers during cutting, thus providing exceptional edge finish quality. The 66-500 Series is a multi-flute composite router for either roughing or finishing applications. Depending on the application, this series has three standard point styles; burr, end-mill and drill. For a universal range of roughing, semi-finishing and finishing applications, the 66-750 Series provides a low-helix design for increased radial depth of cuts with better chip evacuation, resulting in longer tool life. The 66-775 Rougher Finisher Series combines a roughing and finishing design for reduced cutting time while providing a good material edge finish. With an optimized geometry to eliminate delamination, the 66-800 Compression Series is designed to improve shearing of the fibers during cutting. This series is available in four- and six-flute geometries. Booth B35. www.onsrud.com Aerospace-grade (Type IV) pressure vessels MasterWorks Inc. (Taneytown, MD, US), a Hexagon Composites Co., is displaying a range of composite products from the aerospace, commercial and oil/gas industries. New this year, MasterWorks is featuring a Type IV composite overwrapped pressure vessel (COPV) developed for the aerospace industry. This demonstrator unit has successfully passed numerous tests, including cycle, vacuum cycle, burst and cleanli- ness verification, and is currently undergoing long-term permeation testing. Also featured will be filament winding machines, fiber tensioners, resin baths, curing ovens, payout tooling, mandrel extractors, cut-off saws, pressure test systems and material handling equipment. In the booth, a tensioning system will again be a focus because capability has increased to include tensioning on the gram scale at high-speeds.
