IsotropieL'isotropie caractérise l’invariance des propriétés physiques d’un milieu en fonction de la direction. Le contraire de l’isotropie est l’anisotropie.

| Résumé : |
In the lightweight construction sector, the focus is on the development of high-strength materials at low mass. Carbon fiber-reinforced polymers (CFRP) have proven to be particularly efficient. However, the production of primary carbon fibers is energy and cost-intensive - the use of recycled carbon fibers (rCF) processed into nonwovens for CFRP components is more cost-effective. Disadvantage: the strength properties are lower than CF-based CFRPs. The increase in partial strength properties could be achieved by means of targeted preferential alignment of the rCF in the nonwovens. In the project ProStAir, the airlay nonwovens formation process for CF and rCF was investigated. The central question was whether and how the orientation of the fibers of the nonwoven (isotropy ratio) can be influenced when manufacturing parameters change. |
