The trend in construction of new vehicles using lighter weight substrates continues. According to an article by MPower, much of the focus is placed on aluminum but many automakers are turning to carbon fiber not only for exterior components but also complete inner body structures. Some of Volvo’s hybrids inner structure are primarily carbon fiber. This reduces weight and enhances rigidity. Carbon fiber is also in the Silverado/Sierra trucks where GM is using carbon fiber in the construction of new bed assemblies. Industry analysts predict a compound annual growth rate of the automotive carbon fiber market between 7.9 percent and 10.6 percent for the coming five years.
