The battery packs of our racecar have to be fireproof. Therefore, the firewall needs to be manufactured around them to keep them safe. One of the layers of the firewall is this yellow material, which is called kevlar. Kevlar is very durable and is also very common in the construction of bulletproof vests. We would like to thank Siamidis SA for providing us with a big amount of kevlar, which will be used throughout the powertrain and chassis subsystems.
