Behaviour of CFRP during flights verified precisely

摘要

The aim of the measurement flights was to obtain solid data that can be compared with the theoretical calculations of the flight behaviour of carbon fibre reinforced plastics (CFRP). The real data require aircraft manufacturers to build components so precisely that they can withstand the stresses that occur in the respective aircraft model. This has so far only been possible by approximation. As a precaution, aircraft manufacturers are over-dimensioning CFRP in new models. "CFRP structures behave differently during a flight to those made of aluminium," says Conchin Contell Asins, scientist at the Fraunhofer Institute for Structural Durability and System Reliability LBF in Darmstadt. She and her colleague Oliver Schwarzhaupt determined exactly how this happens by using a special test set up during the test flights.
