Strong and lightweight, carbon-fiber reinforced plastic (CFRP) offers numerous benefits to automotive and aerospace manufacturers. Many engineers are intrigued by potential applications for the material, yet remain frustrated by joining challenges.
Carbon-fiber composites offer a variety of advantages for car and truck manufacturers, including lighter weight, better corrosion resistance and higher impact strength than aluminum and steel.
MOBILE, AL—Broetje Automation, a supplier of automated machinery for aircraft assembly, has opened a facility here to support Airbus’ new assembly plant.
EVERETT, WA—Less than 6 months after Boeing broke ground for its $1 billion Composite Wing Center here, the skeleton and super-structure are rising at an impressive pace.
Several big hurdles need to be overcome before there will be more widespread use of carbon-fiber composites in the auto industry. Major issues include material cost, high-volume processing, repeatable quality and overall cost effectiveness.
Carbon-fiber composites offer numerous benefits to automotive manufacturers, such as weight reduction. However, they pose a wide variety of joining challenges to engineers, who must choose between adhesive bonding or mechanical fastening. Each assembly process has many pros and cons.

Each assembly process has many pros and cons that must be evaluated.
Traditionally, it has been difficult to manufacture large quantities of carbon-fiber composites. That drawback has hindered widescale use of the lightweight material in the mainstream auto industry. However, engineers in Germany have developed a new process that makes it possible to use injection-molding technology.
A European consortium called ACOMPLICE (Affordable Composites for Lightweight Car Structures) recently embarked on a two-year program to develop low-cost materials for mainstream automotive applications.
