The Nuna9 solar car has won the Bridgestone World Solar Challenge 2017, as a partner to the Nuon Solar Team, Aliancys supplied its styrene-free Beyone resins for the construction of the outer shell of the vehicle.
The Nuon Solar Team, which consists of 16 students from Delft University of Technology, the Netherlands, took 4 days and 6 hours to complete the 3000 km race from Darwin to Adelaide in Australia.
This was the ninth time that the Nuon Solar Team had participated in the race, having already won six times before. In this year’s challenge, the organization committee significantly adjusted the rules for the participants. This represented a great challenge for the car design, but also brought down the average speed during the race.
“Because of the new game rules, the participating cars are very different in design," explains team leader Sander Koot. "No one knew which team would be the best to cope with the new rules. Fortunately, our choice for a compact design and for using Gallium solar cells turned out to be very right.”
This year, the Nuna9 had an average speed of 82 km/hr. Two years ago, the team's car had an average speed of 91.75 km/hr.
The Nuna9 vehicle was built at the Polymer Science Park in Zwolle, the Netherlands, next to the Aliancys R&D Centre.
“Aliancys supported the Nuon Solar Team with innovative composites application technology, and provided hands-on support in manufacturing,” reports Paul Vercoulen, CTO of Aliancys. “The construction is stiffer, stronger and lighter compared to previous Nuna versions, which means a faster, safer and more energy efficient car.”
Nuna9 was constructed using Beyone styrene-free resin systems used in combination with TeXtreme carbon fibre fabrics supplied by Oxeon. According to Aliancys, its sustainable Beyone resins feature close-to-zero smell and solvent emissions, and are environmentally preferred alternatives to conventional styrene-based resin systems. The resulting Nuna9 vehicle is said to combine light weight, great aerodynamics, and dimensional stability at elevated temperatures. The car weighs 141 kg, has a 2.64 m2 solar panel surface area, and 20 kg battery weight.
