High performance carbon fiber reinforced plastics (CFRP) have firmly established themselves in modern airplanes. Repairs, however, are very laborious and often even impossible. Most of the time the entire component has to be replaced. The PYCO Research Division at the Fraunhofer Institute for Applied Polymer Research IAP in Potsdam, Germany, has developed a simple, cost-effective and energy-efficient way to make sustainable repairs. Moreover, entire components can be completely recycled in a process in which the expensive carbon fibers are reclaimed. Researchers will present their developments at JEC World in Paris from March 8 to 10, 2016 in Hall 5a, stand R93.
