Polestar Conducts Crash Test Evaluating Carbon Fiber

Nov. 13, 2018—Polestar has undertaken the first of a series of crash tests as part of the development of the Polestar 1. This represents the first time the Volvo Car Group has assessed the strength of a carbon fiber-reinforced polymer body in a real crash situation, reported CompositesWorld.

In contrast to a steel body, where bending helps the integrated crumple zones to reduce the amount of crash energy that reaches the vehicle’s occupants, carbon fiber dissipates energy by cracking and shattering.

According to the report, close attention was given to the way the carbon fiber body of the vehicle reacted to the extreme forces involved in the impact. The engineers also focused on how the underlying steel body structure, and carbon fiber “dragonfly” which strengthens it, managed the forces.

The Polestar 1 verification prototype, part of the first Polestar 1 build series, was propelled into a stationary barrier at 56 kilometers per hour, simulating a frontal collision.
