THE COMPOSITES ENGINEERING SHOW EXHIBITOR PREVIEW

number of advanced component fixturing methods, including the novel use of ice to securely hold composite components. The company’s stand will feature a range of AMCC ice plate solutions, designed specifically to hold delicate and flexible components during machining operations. Managing director Mark Jones explains: “Clamping with an ice film allows composite parts to be held rigidly without deflection or distortion and no mechanical stress is transferred to the part. The technology is also ideally suited to applications where vacuum or magnetic fixturing could not be applied. For instance, when the components have through holes or the material is non-ferrous.” A new epoxy composite system, Biresin CR84 is to be


introduced by John Burn (stand 302) at the show. Manufactured by Sika Tooling & Composites, the system is particularly suited to filament winding due to its viscosity characteristics, good wetting out properties and a very long pot life as well as low cure temperature. However, the product can also be used in hand laying processes. Biresin CR84 has also been modified to reduce the dripping


machining or trimming carbon fibre reinforced polymer materials, SGS Carbide Tool (UK) (stand 405) has recently launched the Series-20 CCR (Carbon Composite Router). SGS has worked with a major North American aerospace manufacturer to develop the router, which as well as eliminating the risk of fibre breakout and sheet delamination, uses a patented even helix flute form and chip breaking geometry to provide a reduction in the cutting forces required, and thus a smooth machined finish. The company also claims that in cutting trials on various


carbon fibre weaves, the new Series-20 CCR tooling lasted at least twice as long as PCD (polycrystalline diamond) tooling. The uncoated routers are designed to cut dry or with flood coolant to remove the fine dust abraded from the carbon composite component and are available with and without end cut for edge trimming or plunge machining.

from the fibres during winding, ensuring both high quality components and a clean working environment. The pot life of the epoxy when used with the Biresin CH84-20 hardener is around 10 hours. The resin system can be cured


at 70°C to give a glass transition temperature of approximately 80°C. Finally, epm: technology (stand 210) will be using the


event to ask visitors their opinions on how composites firms should best serve the aerospace industry. The Derbyshire- based company, currently a key supplier to the F1 sector, sits in the centre of the East Midlands aerospace cluster and considers the sector as the next logical step, backed by a £400,000 investment in new equipment. The composite specialist has already worked on a number of projects in the motorsport, luxury car, defence, health and transport sectors, and in a recent project, manufactured four sets of carbon fibre hands for the world’s largest mechanical clock in Ganzhou, China.
