Thick-section carbon fibre composites technology
Vol. 18, No. 7, Page 10 PERA in the U.K., with three industrial companies, has recently completed a Department of Trade & Industry sponsored project to investigate techniques for the production of a large carbon fibre The steel lever chosen for the lever for a high speed machine. case study application weighed over 160 kg, and reciprocated at 160 strokes per minute under a load of 10 tonnes.

The replacement carbon fibre lever, achieving a 50% weight loss, has already been evaluated on a production machine at speeds of As well as increased efficiency, up to 270 strokes per minute. the carbon fibre lever demonstrated reduced vibration andnoise, and increased fatigue resistance. Considerable strides have been made in the moulding technology The final mouldings consisted of over for advanced composites. 110 plies of carbon fibre pre-pregnated epoxy sheets, consolidated under controlled moulding conditions of temperature, pressure and time, to produce a laminate with a final moulded thickness of 30 mm and a void content well within the design allowables. The work carried by the PERA/Industry consortium has demonstrated that it is technically viable to mould thick section, heavy duty components in carbon fibre reinforced plastics. PERA is planning to undertake a further project, on a collaborative basis, to exploit the technology already developed by considering the design and manufacturing requirements of additional case studies which typify engineering components used throughout industries as diverse as transport, textile, compressors and heavy engineering. It is envisaged that the total cost of this work will be e480,000 Companies interested in becoming and take two years to complete. involved in this further work should contact Gerry Boyce, Head of Advanced Composites at PERA, Melton Mowbray, Leicestershire, LE13 OPB.
