Dual Success for Hexcel Prepreg

08 December 2009

Late last week saw the climax of the Jacques Vabre transatlantic race, which yielded a dual victory for Hexcel as boats using the company’s prepregs won in both the mono and multihull categories.

Crepes Whaou! won the Multi 50 race, skippered by Franck Yves Escoffier and Erwan Leroux while Safran’s skippers Marc Guillemot and Charles Caudrelier Benac won the Open 60 monohull class.

HexPly carbon/fibre epoxy prepregs are used extensively for hull, deck and other structures in both boats. The carbon fibre reinforced prepregs are impregnated with the popular HexPly M10 epoxy resin, which has a flexible cure cycle ranging from 85°C to 140°C.

The HexPly prepreg tape supplied for both boats is reinforced with a range of High Strength and Intermediate Modulus carbon fibres. HexTow IM9 and IM7 carbon fibres are used for the Safran centreboard structure and foils to provide high performance and toughness in the “slamming” zone that is placed under great stress from wave impact.

Hexcel say that their product, HexPly M10, provides very high resistance to fatigue in aggressive environments such as sea water. The combination of low temperature cure at 85°C and a long outlife of more than 60 days, with strong mechanical performance, makes HexPly M10 particularly suited to the marine industry.
