of a Rohacell core that can be combined with low-density wooden spars make it possible to develop extremely competitive structures, an example being the "Pierra Menta Pro Carbon" ski, weighing in at less than 750 g Fig.2(b). Glass fibre fabrics predominate in alpine ski structures (due to their yield strength and breaking strain), although hybridisation with aramid or basalt fibres also enhances the potential of our composite structures, both for competition and right across our ranges, for improved damping characteristics and hence better ski-snow contact quality, as sought after by expert skiers. The Rossignol group began to innovate two years ago in terms of sustainable development with the introduction of flax fibres in the manufacturing of skis. In the framework of an in-house programme, "Echo for life", we pursue five environmental objectives: 1) Use of natural materials: 20% of the fibres used are natural flax fibres. The cultivation of this plant requires very little water. The ski core is made of poplar wood from sustainable forestry. 2) Material savings: 50% less ink used, reduced quantities of plastic: 10% less compared to existing models. 3) Controlled production facilities: this ski is produced in our ISO14001-certified factory. 4) Use of recycled materials: base composed of 25% recycled materials. 5) Favouring local production: flax produced in France, wood from Spain where the ski is manufactured. The damping properties of flax fibre also generate improvements in the way the ski behaves (soft feel of the ski on snow), with the female clientele particularly in mind Fig.2(c).
JCM: What are the main manufacturing methods: prepregs, RTM, injection moulding, filament winding ... Are these subject to change?

and experts in the Savoie department of France, the most ecological outlet for end-of-life skis consists in collecting the skis from shops, grinding them down into fine chips in order to extract the ferrous and non-ferrous metals (material recycling), then using the rest (wood, thermoset and thermoplastic resins) as fuel for the cement industry (energy recycling). As from this winter, Rossignol and Dynastar are running a pilot scheme in partnership with Sport 2000 to collect in-store, along the lines of the "used-car bonus scheme" (special offers when purchasing a new pair while trading-in an old pair), and will implement the dual-recycling as described above, in cooperation with specialists in the industry.
JCM: Is it possible to quantify the amount of glass used worldwide in ski manufacturing, based on an average weight per ski and the number of skis manufactured today?

N. P. : Our industrial history in ski manufacturing dates back to 1907, and has incorporated different technologies and processes right through to the present day. The composite processing method used in the ski industry is hot compression and/or injection moulding, and wet layup is widely used in all our workshops.
JCM: What is the situation with regard to the recycling and/or destruction of end-of-life skis?

jec composites magazine / No64 April 2011

N. P. : Far from our mountain ranges, the skis of private individuals that currently end up on waste dumps are, unfortunately, consigned to landfill, since the highly powerful beam gluing process means that the ski can be neither dismantled nor recycled in its current condition. At the initiative of local authorities

N. P. : Compared to the construction, transport and energy sectors, the estimated proportion of glass currently used in the ski industry would represent 0.15% of the 3,800,000 metric tons produced!
