Aramid protective sheath for Audi e-tron
The testing included a climatic shock resistance test with a temperature range of +80°C to -40°C and a temperature shock test from -40°C to max. +95°C. The requirements are no changes in tensile strength. Resistance to moisture was also tested under conditions of 40°C for over 400 hours. Since the joints represent a potential weak point, it also had to pass a seam test.
The aramid protective sheathing proved to be an additional safety factor in all scenarios.
