Composites 101: Fibers and resins

Compared to legacy materials like steel, aluminum, iron and titanium, composites are still coming of age, and only just now are being better understood by design and manufacturing engineers. However, composites’ physical properties — combined with unbeatable light weight — make them undeniably attractive.

Carbon Fibers

“Give us affordable carbon fiber!”

Guest columnist Dan Pichler, managing director of CarbConsult GmbH, suggests that the we need a sustained, cooperative effort in the carbon fiber supply chain. Partnering is the key.
