CARBON FIBER MATERIAL IS ESSENTIAL FOR<br />

LIGHTWEIGHT PRODUCTION OF THE <strong>BMW</strong> i3 AND i8.<br />

Main arguments for the utilization of carbon fiber materials:<br />

• Low weight:<br />

CFRP parts are approx. 50% lighter than comparable steel parts and<br />

approx. 30% lighter than comparable aluminum parts<br />

• High tensile strength/stiffness:<br />

CFRP has excellent damping characteristics and high energy absorption<br />

in a crash<br />

• Corrosion resistance:<br />

Avoidance of expensive protective coatings as CFRP is resistant to<br />

corrosion, acid and solvent<br />
