Twaron with circular content, developed by Teijin Aramid, will help power one of the world’s most advanced solar cars in the 2025 Bridgestone World Solar Challenge.

Covering more than 3,000 kilometres from Darwin to Adelaide through the remote terrain in the Australian desert, the Bridgestone World Solar Challenge is the world’s leading solar mobility competition.

The Brunel Solar Team, based at Delft University of Technology in the Netherlands, has earned multiple titles since its debut in this race in 2001 and in 2025 will race its latest Nuna 13.

The tyres for the Nuna 13 will feature Bridgestone’s Enliten technology, combining a range of recycled technologies and including a new version of Twaron aramid containing circular material in the tyre belt. Enliten ensures the low rolling resistance, durability, lightweight construction and puncture resistance to support safe and secure driving for the journey of approximately 3,000 km under harsh conditions.

Twaron with circular content delivers the strength, thermal stability and lightweight properties of standard Twaron with the added benefit of supporting a more circular aramid production process.

Inside the vehicle, a protective flame-resistant shield made with Twaron fabric has also been installed around the driver area, offering enhanced safety through its strength, thermal stability and low weight.

“Every material choice we make is intentional,” says Daan van den Dries, chief engineer for the Brunel Solar Team. “Twaron gives us the strength, protection and weight reduction which we need to perform at the highest level while also lowering our environmental impact with recycled or circular material.”

“Seeing these two types of Twaron being used in this solar race car is a powerful example of how our partnerships, be they with large corporations or students, really drive progress,” adds Peter ter Horst, CEO of Teijin Aramid.
