Chomarat has developed a unidirectional carbon fibre woven tape for its C-TAPE line, designed to facilitate series production, which is being employed in the foils of the Figaro Beneteau 3.
“For the series production of the foils, the Beneteau Group chose Multiplast, the well-known builder of racing boats, which engaged the Chomarat Group to provide project support and achieve the best cost/performance balance,” explains Vincent Cholvy, Chomarat’s Manager for the boating market.
According to Chomarat, C-TAPE offers a lot of flexibility in terms of weight, width and construction. It has been optimised to facilitate series production, yet provide the foils with maximum performance. The weft yarn developed by the company makes the tape easy to handle and work with. It is produced in 50 cm widths in order to adapt better to the mould, thus reducing both scrap and production cost.
“The project was an ambitious one,” says Multiplast General Manager, Yann Penfornis. “We had to reach a lower target cost, achieve a perfect foil shape, guarantee identical weight for all parts, and produce a set of foils per week over a period of one year.”
Fifty plies of tape are used to make the foil so that it can resist high levels of stress and achieve optimal performance. The structure of C-TAPE facilitates resin flow throughout the thickness. The reinforcement provides the desired mechanical performance and also cuts down on production time. The result is an innovative foil, both in terms of its geometry and its fabrication process (infu-jection).
“This new C-TAPE is the fruit of close co-operation between the Multiplast and Chomarat development teams, and it rounds out our broad range of tapes,” concludes Cholvy. “We are working on different fibres and adapting the widths to our customers’ processes in order to reduce costs.”
By the end of summer 2018, some 100 foils will have been produced for assembly on the first 50 Figaro Beneteau 3 monohulls.

The Institute for Advanced Composites Manufacturing Innovation (IACMI) has announced the Phase I completion of a project led by DuPont, partnering with Fibrtec and Purdue University, focused on the creation of a new carbon fibre composite manufacturing process that exhibits improved fabric formability characteristics compared to traditional woven materials.
Powertrains, be they conventional, hybrid or fully electric, will need to be light in weight if carmakers are to meet the stringent regulations on carbon dioxide emissions (CO2) to come into force in 2025 – and composites will be key to making this happen. This was the message highlighted at the Lightweight Composite Solutions Conference organised by Vyncolit and Sumitomo Bakelite Co Ltd and held in Gent, Belgium.
At SAMPE 2018 in Long Beach, Technical Fibre Products (TFP) will exhibit its advanced nonwovens, including the Tecnofire fire protection range, nano-coated materials and coated materials and Optiveil lightweight veils which aid surface finish and composite fabrication.
