, the Plastics Technology Centre (Valencia, Spain), reported on June 9 that its EU-funded RECONTRANS project — developing multi-material thermoplastic parts as a light weight, cost-effective solution for sustainable vehicle design — obtained its first three prototype samples in the automotive, truck and rail sectors.The three demo samples include the door of a car, the rear suspension of a truck cab and the interior panel of a train coach.

Aimplas says the three samples obtained were manufactured with Arkema’s (Colombes, France) Elium thermoplastic resin, which has been adapted for microwave curing and welding. Aimplas manufactured the automotive and truck demonstrators using resin transfer molding (RTM) and pultrusion to reduce fabrication time and energy consumption. The hybrid welding process was used for metal-polymer joining of the truck and train prototypes to reduce raw material waste and improve the standardization and automation of the production process. The institute also notes a production line monitoring system kept tabs on the entire process.

Aimplas says progress in the project’s 30^th month shows that, following the manufacture of the first prototypes, significant cost and energy consumption reduction was achieved compared to conventional composites, and that it provides a feasible process for recycling and for processing recycled thermoplastic composites.

The RECONTRANS project, started in October 2017, will end in October 2021. With a total of 13 partners from seven countries taking part, Aimplas says the developments carried out in this project will be applied to other sectors as well.
