Kevlar is a high-strength, lightweight material used to make Formula 1 car. This material is known for its superior strength-to-weight ratio. It is specially used in cockpits and survival cells to protect the driver in crash events.
This synthetic fiber is five times stronger than steel but more lightweight and flexible. It is made from a polymer called poly para phenylene terephthalamide. Kevlar is used in F1 tires and bodywork construction.
The outer layer of the F1 car is made of Kevlar and it is penetration resistant. At the same time, during a clash, this outer layer absorbs a huge amount of energy to shield the driver from any injury.
