How to Control the Density of Vehicle Panels?

Last time, we introduced how to increase the rigidity of vehicle panels. Glass fiber is a good choice. Today, let’s move on to the density.

The lightweight solution of vehicles generally refers to thinner walls and lower density. Of course, thinner walls should be based on sufficient modulus. Without modulus, lightweight becomes jerry-built. According to the last discussion, high modulus comes from the draw ratio. Glass fiber and talcum are common materials with a high draw ratio in vehicle panels.

Less thickness and lower density are the main directions of lightweight vehicles. Nowadays, only 5% glass fiber can achieve the strength of vehicle panels.

The above picture shows a lightweight vehicle material in the Dusseldorf Exhibition 2019. TOPOLO is professional at such materials and providing lightweight vehicle panels.
