Alstom ETR 675 Benefits from Core Composite Solution

With a core composite solution using infused Divinycell P60, Diab and business partner Chimpex have made a light yet sturdy nose for the Alstom high-speed train ETR 675 for NTV (Nuovo Trasporto Viaggiattori), a private transport companies network in Italy.

Founded in 1989, Production Group says it has multiple facilities in Italy and it is an IRIS certified, national leader in the design, development, manufacturing and maintenance of components primarily intended for the railway and mass-transit sector. Its products are used in several major railway systems across the globe, from high-speed 'tilting' train to urban driverless tramways and metros.

Today, Production Group explains that it focuses mainly on the production of aerodynamic vehicle front-heads, pilot cab interiors, roof and external fairings, energy collecting pantograph systems, complete toilet modules and passenger cabin furnishings. As a market specialist in aerodynamic front-heads and other fibreglass-reinforced resin components of high-speed fleets, Production Group says it has played a major part in the construction of the new Pendolino high-speed train project. The specialist position has been further confirmed by a new commission to design the high-speed aerodynamic nose and front of the new Italo Train ETR 675.

The project brought together Diab and long-time business partner Chimpex Industriale. Together they say they have contributed to the development of the material required to enhance the mechanical properties and concept of the FRP sandwich solution to be used for the ETR 675. The aim has been to save weight while keeping the stiffness of the material. With an infusion process, it has also been possible to meet the stringent FST (fire, smoke and toxicity) requirements of the industry standard EN 45545-2, which regulates fire safety on trains across the European Union. Divinycell P60, with PSC/GRC finishing, was used to realise all sandwich parts of the nose, with a difference in thickness depending on the stiffness and weight requirements.

According to Production Group, Diab and Chimpex were chosen as partners due to their knowledge and expertise, focused approach toward the project and their policy on long-time partnership. In the high-speed train sector, where a continuous R&D process for new highly technical products is required, Production Group says it can trust the commercial soundness of both Diab and Chimpex, with their material availability, consistent quality and continuous R&D process.
